This is gonna sound like a troll post but i assure you it is not.
I don’t have a coding background but I’ve used Teams in a lot of workplaces and really only encountered like 2 issues entirely.
Either I got seriously lucky or it was before enshittification.
Why do you yourself dislike it? Is it UI? Performance?
I should also say I use Teams for basic purposes like messaging and uploading files, I literally don’t touch anything else and performance hadn’t been an issue. (Likely because I’ve been given thicc-ass workstations in the past)
Heads up, you can see multiple calendars at the same time. The apps thing is interesting because you can embed things like PBI dashboards into a channel, making it easy for everyone to access. It is possible that the configuration at your work is preventing these things. But even when properly configured, everything is just 16 easy clicks away. Ugg.
I guess there is an update I’m missing
It is like a quest I’m on with MS to let them know that poor configuration is the number one impediment to their products. Users can’t tell the difference and assume it is always MS, when it is only them a portion of the time. 😉
