Hi @jmilbrink, thank you for posting in the community. We are currently taking a closer look at the issue you’ve described and will update this thread as soon as we have more information. 

Thank you for your patience and please don’t hesitate to let us know if you have any questions in the meantime. 

@Leianne C, the LucidChart tab I added is now being displayed in my Teams for Mac. I also successfully added a second LucidChart tab. So it appears there isn’t a problem anymore. No idea why it started working. I never rebooted, I had already tried quitting and re-opening Teams to no avail, and I didn’t change anything. The only thing I did was I moved my Mac to another location, which means I paused the machine for about 1hr while in transit. Sorry if I caused you to waste some time on this one.

Thank you for the update, @jmilbrink! I’m glad to hear the issue is resolved. If you experience the same behaviour again, I would recommend giving the steps my colleague shared in your other post a try:
