Thanks for information on key areas of change/update to build 20190225
To clarify my second point, I installed build 20190227 this evening. (You removed 20190225 build and replaced with 20190227?)
1st I attempted to install tar file of 20190227 build into update folder of my VIM2 whilst it was up and running on my network (20190211 build)
Then rebooted VIM2 to in theory allow it to perform a restart and automatic install of 20190227 over existing 20190211.
As previously mentioned "just for general information" this method of updating to latest build onto SD appears not work. No problem at all, just providing feedback as this method of updating works for other frequent alpha/beta builds.
In order to get to my previous LibreELEC set-up with few addons installed/configured etc, I made use of available and very good LibreELEC backup option in LibreELEC settings, to create a back-up before installing your latest build (clean img.gz build onto wiped SD using "LibreELEC USB-SD Creator" ) then used backup restore; to get back to my previous addon setup, with your latest build.
Note: Above method of works well, avoiding a manual setup of addons I require after every update to your latest build
