I wish... I'm on Windows 11 Enterprise with corporate Teams, definitely 100% Microsoft approved combination and:
- on one channel my message never got sent, while on another channel it does work
- sometimes when I scrolled up the old messages doesn't show up, with a 'message removed by organization retention policy' text.. but those are messages from yesterday and sometimes when I restarted Teams it shows up again.. sometime it doesn't but when I opened web Teams it does show up
- sometime I can't connect to Teams for no reason, restarting Teams and computer doesn't help either, went to the IT helpdesk and they spent several minutes redoing what I did until they just googled it and delete the cookies or something
I also used slack and from my perspective its 100% reliable at delivering text messages
