Want to be able to use/enable both documents editor at the same time with AIO

I wish to be able to use both editors at the same time.

Some of my users has .doc, .xls, those previous gen MS office files. Tried with Collabora ecosystem and is not editable.

Is fine for me if I can’t select both documents servers in AIO interface.

I know how to deploy document servers. That’s how I began with.

When I installed Onlyoffice via the app store, after configuring it, the loading circle never go away.

Can’t save settings

And when I restart AIO and/or the server, OnlyOffice will be uninstalled. I have to reinstall it after each reboot
