Hello,
I noticed an issue on Android with the new FilterFeedbackBar where the FastFilters disappear. In my case, it happens after the following steps:
1. Open a page with FastFilters
2. From there, open a subpage via ObjectTable
3. Lock the device
4. Unlock the device
5. Go back to the page with the FastFilters
Here are pictures what it looks like at first

And what it looks like after the steps have been done.

This only happens on Android. In iOS, this issue is not present. Tested on Android 10 and Android 13.
