MS Teams - other users see old profile picture
I regularly change my user profile picture (corporate teams account) and after a short period my profile updates across the O365 environment. However users in MS Teams typically see older images cached (from a previous meeting) on their side when we meet in teams. In other areas (eg; Outlook person card or SharePoint/Delve) they always see the correct photo.

This is an important topic as it relates to personal information in the GDPR context, especially where a user changes their mind and "opts out" of allowing their picture to be used. I am going to vote here and look for another possible topic which is related to that.
