Replying to @AskWorkspace
@AskWorkspace Is it normal to lose edit access to all files in Drive after upgrading Workspace subscription to Standard?

Straight after upgrading, all our users were no longer able to edit any sheets or docs, and get a red warning that we have gone past our "0 bytes" storage limit.
