I have collabora online CODE server installed but i can’t see the icons for documents etc. Has this been disabled on the nextbox?
I think Collabora still doesn’t work on Nextboxes, and I don’t know why. Se here and there…
You may try OnlyOffice -and if you do so, please come back here to tell 
Thanks for the reply.
If it just doesn’t work, nitrokey should just disable it in nextbox rather than have redundant features selectable.
I’m not sure they can ; their principle is that while they fully handle the Nextcloud embarked on the Nextbox for you, on the other hand they allow you to install each and every application you want…
OK you are right in the sense they modified the core Nextcloud updating process, so they probably can do the same for apps…
