This reminds me of the situation at the school I work in.
We are an MS school and a MS system can become quite complicated to set up and maintain, esp for a sus admin of the calibre that a schools budget can afford.
We went O365 at the start of the pandemic, MS Teams/Onenote for remote learning is "sup optimal".
Two years in and we still do not have OneDrive installed, only the browser version. So no file manager integration...
We have been told that all our files are being moved into the cloud now, and we have been promised OneDrive "hopefully in 2022"....
How is this supposed to work?
(By the way why does file syncing take so long in O365? I mean, it can take hours at times. When I worked at a Google school syncing was near as made no difference instant)
