Hey, everyone. We’re using the latest App Bridge, and today merchants are reporting that the Shopify navigation appears on top of any Fullscreen experience. Looks like a few folks on X are seeing the same too. Can anyone from Shopify take a look at this?
We were able to narrow it down to a specific CSS property. Not sure if that was added earlier today, but it’s definitely the cause.
Hey @sandy-stoq,
Just curious if you’re using fullscreen or a max modal for this
I believe fullscreen mode is technically no longer supported in app bridge, so you may need to update to a max modal, although it’s definitely unfortunate when Shopify makes breaking changes to app UIs 
We’re using Fullscreen; sorry I should’ve made that clear. It looks like apps using max modal are working a-okay. Someone from Shopify was kind enough to acknowledge the issue; we may have a fix soon! 
We’ll definitely upgrade to max modal in the coming weeks, but this looks like a bug slipped through.
This was affecting App Bridge >v3’s fullscreen feature and the bug should be patched now. Let me know if it still persists after a refresh.
