Hello,
take care with updating Collabora Online 4.2.4 (published yesterday) in Nextcloud 21.0.7 and Collabora CODE 6.4.10.10 - do a backup of your system, before you update to it.
Today I updated Collabora Online app in Nextcoud 21.0.7 from 4.2.3 to 4.2.4.
I am using the latest Collabora CODE 6.4.10.10 from Univention App-store, which still is the latest recent version for several months successfully.
But after updating I cannot open documents anymore.
