You can request mobile app support by kindly emailing OnlyOffice directly at support@onlyoffice.com
No longer relevant, but I’ll leave here any case anyone runs into this issue…
I see the option to login into personal or portal accounts via the official OnlyOffice Android App. I’ve tried logging in with both options unsuccessfully. Also tried using my main password vs. one-time passwords with no success.
Asks for my.server.com domain, user name and password. Perhaps personal Nextcloud instances are not supported at all… I see users can use OnlyOffice’s own cloudstorage, Facebook, or Google credentials to create a supported account.
Oh sorry; On their Play Store screenshot it shows the option, but when I try to do it on my App there is no option to select another service besides OnlyOffice. Possibly their marketing department is moving faster than their production team.
No, it works with their Community Server, which you can also selfhost, but it mostly duplicates the features of Nextcloud. There is an option in the community server to link to Nextcloud via WebDAV which works fine.
