Answer 3

I've spent way too many hours to keep this to myself. The way I fixed it was that I noticed some hours later that I was using different layout version in res/ .... I have actually two versions of layout (layout-v26) and (layout). All this time I was modifying the other one and uploading different one. Maybe its just a newbie mistake but I hope somebody will find it useful.

The reason why there are 2 version was because of " autofillHints="" -> quickfix -> create new version of layout "
