Hi, I experience the same problem, and I have not tried the workaround mainly since I hope that a permanent solution will be available soon and that I'm not that comfortable doing the workaround.
I'm a less experienced user that uses WinSCP to access the Libreelec system on my Wetek Play 1.
So, my question is really - when can permanent solution be available or do I need to use the workaround for each update from now on?
I've been having the same problem. The system was running fine on LibreElec 8.0.2 and after the upgrade to 9.0.0 I've had nothing but problems with no answers yet this is something that multiple people are reporting now so it's hardly a specific issue with my hardware or software set up and much more likely to be an issue with the 9.0.0 upgrade.
I've tried to downgrade the system the only way I know how and nothing - it's locked into 9.0.0. So at the moment I have a redundant unit!
