Teams calls/notifications aren't syncing across devices

I have the same exact issue and I believe no device mode or connection issues are involved, e.g on my laptop (up to date windows 11) the teams app doesnt show messages while my laptop is always on has more than 20GB of free physical ram and more than a TB of free physical disk space its connected reliably both via Ethernet (1gbps) and WiFi7

I never had connection issues or similar issues in other apps such as snapchat etc.

I may get a message on my phone but said message doesnt show up (at least not always ) on the laptop.

And because I have the same teams account on my phone my tablet and my laptop I noticed that even when it does sync it does it only when I open the app on an other device.

E.g if I chat with person A using my phone and person A sends me a message, my tablet (or my laptop) most of the time dont get this messages but almost always when I open manually the app on the tablet THEN almost always it starts to download and display the conversation, while when with the laptop that's not always the case.

The irony is that my phone and tablet are android but the laptop which doesnt work as should runs windows so its a complete Microsoft ecosystem yet there it is where the teams app works at its worse ...

I think the issue is that the backend it self isnt configured to auto sync across all instances of an account and just does on demand (when an app manually opens with said account) and there is some data loss due to that or timeouts or whatnot.
