“sorry, we can’t take you to this destination at this time”
A pupil go this error on her mum’s android phone trying to get to a Teams assignment the other day. It took a while to back & forth to find out what was going on & to find an answer, a common problem, perhaps, with multiple accounts on android. Our solution was to provide iPad.
Just hanging this here in case it helps, not with my solution but knowing it is a problem sometimes is a comfort. Also as a help to my ever older memory.
