All X1CC printers stuck on 99% firmware update

Howdy mates,
I just gave up and O.K.'d the everlasting firmware & bambustudio update.
First updated Bambu Studio which went perfectly smooth.
Then I went by all printers and just OK’d the ever popping up bubble “Update Firmware”…

Now ALL printers are stuck on 99%
(All my printers are X1CC’s)

Could you please advice how to proceede now?

Should I give it a couple of hours?
Hard reboot?

I put my trust in you mates, youve allways been there when I found myself in need. You make the community awesome mates!
