Upgraded to 1.1.0 RCBugFix. Is my UBL working?

[Renfro]

I see unprobed mesh points on the right and on the top. You can get rid of those (fill them in) with a G29 P3 T

Done! It did change some values, but I don't really understand whats going on here:

Well... It depends on how you want the system to operate. I want the bed leveling system alive and working when the machine powers up. If you want that behaviour, you do a G29 S1 to save your mesh. Do a G29 F10.0 to set the fade height. Do a G29 A to activate the system. And then do a M500 to save the current state.
When the system powers up, it will automatically load mesh 1 and the system will be active. In this scenario... You never need to do a G29 but the system will be alive and working.

Followed your guidance here step by step (G29 S1, G29 F10.0 + M500) still it returns "Unified Bed Leveling System v1.01 inactive." for a "G29 W" after a reboot followed by a G28. Is it supposed to be like that?

Are you using the G26 Mesh Validation Tool?

Yeah and the printed pattern looks pretty good to me. Got 100% adhesion with the right amount of pressure.
