Limitations with OnlyOffice

ONLYOFFICE officially offers different versions of its online document editors packaged as ONLYOFFICE Document Server: Community, Enterprise and Developer editions. Since, the Enterprise editions are proprietary offers, we only offer OnlyOffice Community edition.

Mobile editing limitations

Currently, it is not possible to edit documents on mobile if your instance is using OnlyOffice. 
Mobile editing was possible on previous releases of OO, but it was removed and after a community backlash it was added just to be removed again and to be released as a paid feature. You can read more on this thread https://github.com/ONLYOFFICE/DocumentServer/issues/805

If your team was previously editing on desktop and now is moving more to editing on mobile devices. We would suggest opening a support ticket and request for your instance to connected to our Collabora server.
If you really need to edit on mobile on OnlyOffice, you can check their prices here https://www.onlyoffice.com/workspace-prices.aspx#workspace-on-premises
