So please set the cloud backup to on in settings, then enter the access data in the user area. It is better to turn on the syncronisiation, I admit the name 'cloud backup is confusing'. and now I can open the updated one from the Nextcloud app via square icon with arrow.this does not work, but the existing database in IOSKeePass disappears.in the Nextcloud app, Open With: IOSKeePass.The only way I found to update the DB file, but it's a bit awkward: I can't even remove the database, to re-add it (just nothing happens when I try).However, it's not picked up by IOSKeePass

I pull down the app page, spinning wheel.I select Nextcloud -> database file (I see it's modified).I click on the icon at the bottom (square with arrow.it is not automatically picked up by IOSKeePass.So I updated the DB file and it's available on the Nextcloud. Not sure if this should happen automatically, but even manually it seems a bit weird. This generally works, but pulling an updated file seems somewhat broken. I have my DB file on a Nextcloud instance.
