Custom Teams background does resize when multiple people on call

[MarkThomas22]

Our marketing team have designed a corporate background for everyone to use with the company logo, etc. When you have a 1-2-1 call (i.e. only on the face on your screen), the background works fine. However, when multiple people join the call, the logo, which is in the top right corner, gets cropped out, and the background doesn't resize for the new-sized window. 

How can this be rectified? I assume this is possible, as the standard stock backgrounds resize and look fine.

Hello Mark,

Are you following the recommendations on size and aspect ratio?

"For the best experience with custom backgrounds, we recommend uploading images with an aspect ratio of 16:9 and a resolution of at least 1920 x 1080 if possible. The higher the resolution, the better your images will appear."
