My issues: Pictures, headers and footers, the amount one can fit in a page (varies between versions). What will happen to the Teams version if I download it, edit in the native app and save?

Downloading a lot of files off Teams usually fails and gives a load of html files.

The ‘integration’ nag for one drive which can’t be dismissed or enabled but seems to work.

It’s an absolute mess and I’m very surprised to encounter someone who finds it works well.
