This item is still under review. I’ll keep following up with the feature team and sharing all your feedback.
We need to notice when we have a Teams message, sounds need to be adjustable to be louder and ideally having the icon flash -- or otherwise draw one's attention visually -- would be great. Skype worked great, Teams is a total disappointment so far - no one seems to notice that I've "same-timed" them.
Please make this a priority, speed up the process of fixing it! Just knowing it is "under review" doesn't provide any assurance of a speedy fix. Thanks much.
