Hello - For the Sidebar Instant App, I discovered that any new sidebar apps created since the February update have a display issue on the Android 14 OS, In my case a Pixel 8 Pro with the April 5, 2024 security update.
When interacting with the search>map layer>popup, the return 'cuts' the display in half on the device:

When just interacting with the Map only> tap:

Sidebar apps built before the February update have no issue with either map tap>popup or search>map layer>popup:

There is not issue with the iOS at 14 or 15
