Has there been an update to the dimensions of the teams backgrounds? March 13, 2025

We are trying to upload 1920 x 1080 custom backgrounds and we are getting an error message saying invalid size. Testing other sizes, anything square 1:1 works but gets cropped in the viewer. We also tried 1280 x 800, but same gets cropped. There isn't mention of this update in any of the update logs. What is the correct size, is there a template to follow to know what gets cropped?

    Unfortunately, avoiding Teams seems to be the solution that works for me...

    Users in our tenant also started encountering this problem. We will check whether the clear cache workaround works.

    UPDATE:

    For our users, the clear cache workaround does not work. Even after deleting the entire

    %localappdata%\Packages\MSTeams_8wekyb3d8bbwe\ folder, the problem persists

    Version we are using right now: 25044.2208.3471.2155.

    We tried all these workarounds but the only thing that has worked was to reduce the size of the original images to 1800x1012px. Then Teams will let you upload them. Smaller works too, as long as they are in 16:9 format.
