 4. xet7 does not have time to answer those, he just fixes the issue - usually at the same day, makes new release, closes all related issues with last comment "Please try Wekan (version-number-here)".
 5. There is [only one comment](https://github.com/wekan/wekan/issues/2812#issuecomment-555860032) that says "This resolved things for me. Thanks for such a quick fix. This is an invaluable piece of software for me!"
