It absolutely ridiculous how many bugs are still present even in the latest ThinOS 2205 release but the worst part is every release of 9.x I’ve tested has introduced new issues that significantly impact the configuration of my devices (including the one reported in this post). As Peter stated ThinOS 8.6 was extremely stable and I almost never experienced any issues. The 9.x release has been a nightmare. The regression testing (if any) that is being performed before each release is pathetic.
