Since nightly and release are affected, beta will likely be affected too.

This is caused by blocking cookie access for cmp.inmobi.com as a tracker.

It seems like the website fixed it or the change from the disconnect list. Do you still see the behavior? We could put this on our allow-list if necessary or close as WORKSFORME.

The record shows that the Cookie Banner is properly displayed when you switch back to ETP standard mode. So, I think this is no longer a ETP standard issue, but a tracking protection issue. It's because we block cmp.inmobi.com in ETP strict mode as an ad tracker.
