This started to happen yesterday.
Previously when viewing photo observations from iNaturalist I was able to scroll down on the far right to maximise my viewing area but that is no longer possible.
I was going to add an image here but access is denied.
If I switch to "View grid in full sceen mode" I go to full screen but have a letterbox view which shows the same amount as on the normal page. There is a lot of empty black space where observations used to be shown.
