Private channels - not reporting membership correctly
We have recently started using Private Channels to allow external guest users to access our Teams. We have an issue where guests were added to a Team but the users were not being reported correctly (i.e. the totals were wrong and sometimes the listed people had people missing). The update log that is stored in the channel seems correct, but the interface doesn't correctly display who has access to the private channel.
Have these inconsistencies been seen before?
Not being able to reliably see who has access to a private channel is a serious issue for us.
