There is always a delay when I receive a message
When someone sends me a message, I always have to wait a long time to receive it, but when I send a message to someone, they receive it immediately. Furthermore, When I change a PC, I can receive messages immediately.
I'm not seeing the delay ALL the time, but I've certainly seen significant delays in receiving messages sometimes, ranging from a few seconds to 28 minutes. This is the desktop app on a Mac, running Mac OS 10.15.7. The version of Teams running on my iPhone doesn't appear to have the same issue.
