Description
I have four layers hosted at the same server. The server is out of my control and I honestly don't know anything about what software it is running. But I know that I have not had any similar issues on QGIS Desktop App when accessing these WFS layers.
I have only tried Mergin Maps Input with GPKG and WFS-T. GPKG works flawlessly and everything is rendered every time. But with WFS-T its less than 50% of the time that it renders. It tends to be when I zoom in that the symbols for the WFS-T layer disappear.
I have tried to demonstrate the behavior in the screen capture below.

Input App: 2.1.1 - android
System: Android (12.0)

Research direction
No source file, test, or entry point is identified. Start by reproducing the WFS-T rendering failure on Android 12 while zooming, using the linked screen capture and comparing behavior with QGIS Desktop. Done means the WFS-T layer reliably renders its symbols after repeated zoom changes.
