Netflix Add-on not working after update from 9.2.6 to 9.95.2 on Raspberry Pi

On one Raspberry Pi 4 with Libreelec 9.2.6 the Nextflix Add-on worked fine. I updated Libreelec to 9.95.2. Several other Add-ons and Netflix Add-on were updated. Now the Netflix Add-on starts as usual, I am signed in, but when I click on a video to stream it I get the error message in my language meaning something like "at least one file can't be played - see log file". I installed the log viewer add-on, it works. Then I installed Kodi log uploader. When trying to upload, I get an error messag - "upload not possible, see log".

On another Raspberry Pi 2 without installed Netflix I updated Libreelec also from 9.2.6 to 9.92.2. Thereafter I installed the Netflix add-on and other necessary software. The same happens there also. When clicking on a video in Netflix I get the same error message as on my Raspberry 4.

What can I do? Uninstall every Netflix add-on related software and start from scratch?

Just noticed that the 9.95.2 is a beta version. No warning when installing it.

That's probably it. I could go back to 9.6.2 but the addons would not.

Thanks for the input. Unfortunately I ruined the whole installation finally. Several addons did not work any more with the 9.95.2 version. I finally realized that this is a beta version. No warning during update. I ended up with a complete new installation of NOOBS having version 9.6.2 on the libreelec/kodi arm. Now I am fighting to get the old version of the castagnait addon to work. I have installed Input Stream Adaptive and Helper and I can get into my account but when clicking on a video, it flashes up shortly and then nothing else happens. A lot of time wasted already

I am using NOOBS to install a Raspbian and LibreElec/Kodi on the same card, since I need both of them alternatively. Finnish TV has ended APIs for Kodi, so the YLE-addon for Kodi has gone up in smoke. The programs can be seen in a browser though, that is why I need the Raspbian, which needs a mouse and keyboard. All other streaming can be done with LibreElec/Kodi/addons which is easy to handle with the TV remote control for all family members. The newest version offered by NOOBS ist the 9.6.2. That is the reason why I was upgrading to 9.52.2 and not a fresh install. I could install the latest version of LibreElec only on a memory card but then I would have to switch memory cards whenever I want to change between Raspbian and LibreElec/Kodi. Now I am trying to get back from scratch to my 9.6.2 config which was working perfectly....

Do you know any other way than NOOBS to install a Raspbian and the latest LibreElecKodi on the same memory card for the Raspberry Pi?

I have installed a plain 9.6.2 version (no NOOBS) on a Raspberry Pi 2. Then I installed InputStream Adaptive, RTMPinput and the CastagnaIT Repository for Kodi 18.X. Then from this repository the Netflix addon, started it, it downloaded the Chrome OS etc etc and announced that installation was ok. But still the same problem as before - I can sign in with my credentials, find my list, the images are displayed in the left bar but when I try to start a video, it just flashes a short moment, thereafter the screen remains as before trying to start.

I must be doing something basic completely wrong every time, since it happens on both Raspberries, just can`'t imagine what it might be.

widevine updates seem to have broken things.

the sentence was ambiguous. "things" can be understood in two ways..

Read here how to downgrade Widevine: Click!

I don't have any previous versions offered since I have made fresh installations on my Raspberries. I could not find any choice of versions during installation either like with addon versions. Can I somehow influence versions of Widevine installed?

Bingo !!! Thanks a lot for the advice!

No more update on a working system without a test on a cloned SD-Card....

NOOBS can be the proverbial PITA.

In this case it turned out to be innocent. It was just pure coincidence that I updated when the widevine which would be installed thereafter, had a critical bug.

An alternative would be to install Kodi under Raspbian and let it start automatically after booting. That would eliminate the absolute need for a keyboard-mouse and still make a browser available without rebooting the RP
