I will try to answer one by one.
As first, caching was enabled at the cloudflare side. I know I left it off but seems like CF enables it after some time on it’s own. So, first I have purged all the cache and disabled cache. Next step was the same as it was the first update. I have updated the UM to 2.1.1 and run install successfully. Not sure if it is normal but even I had um 2.0.56 version installed db was marked as 2.0.54 version before update. Anyway, as said, update was finished successful.
At first look member directory was showing the list. Next thing I tried is to enable list view and return to grid. That worked too. Than I have tried to enable search for admin & administrator roles (as it was disabled for everyone in previous version) without any special filtering. It worked correctly. However, after search was enabled I have lost members in both, grid and list view. The only way to bring the members back was to disable to search function. I believe there is something glichy in here.
Inspecting the console window has showed loads of errors. I am listing you bellow only some of them.

Unfortunately member directories page is accessable only for admin user so I can not link you the members page. Btw, I haven’t created any member directories. Members page simply showing the registered members and that’s all.
Thank you for taking the time to look into this. Hopefully some of the information above will help you locate and fix the issue. Not only for me but for all other UM users. In case you need any more data feel free to request and I will do my best to respond as precise as possible.
