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)
I’ve used it at work for the past 6 years and it’s just quite buggy. Sending an image only works around 50% of the time, calls go directly to voice mail despite the other person being there and waiting for my call, mobile app shows me being in a call I’ve left hours earlier, tabs with things like checklists never load etc. I’ve used worse programs, but it’s far from good. On a positive note though, the background noise filter in Teams is the best I’ve heard.
