Fibaro door/window sensor V2 stopped working

All my connetced Fibaro V2 door/windows sensors stopped working today. They are still online in Smartthings IDE and send temp information but don’t update status change open/close.

In total I have 7 of them and all of them stopped working today.

One of them has a battery status of 255% which looked really weird. Not sure.

If I go into IDE and check one of the particular sensore and press update wo changing anything, the status changes from closed to open, but still doesn’t change back if I close the window.

Everything else works fine, even sensors from different brands.

Does Smartthings have any issues?

Any ideas?
