Version 3.1.x library all fail to load GUI

null@example.com (RemoteSexy1) — Fri, 22 Mar 2024 07:40:47 +0000

I have the latest Android app and I use Arduino IDE from Windows store.
I made a simple sketch with 1 button that sets pin 13 to HIGH so it will light up the LED on the Arduino board.
I am using HC-06 Bluetooth on a Arduino UNO or Arduino Pro mini. Bluetooth is connected using REMOTEXY_MODE__HARDSERIAL and REMOTEXY_SERIAL_SPEED 9600.

If I compile/upload with any of the 2.4.x libraries, it works great. I connect to BT and it downloads the GUI (with 1 button) to the phone. The button works properly by lighting up the LED. Yes, I unplug the USB and use external power.

When I compile/upload with any of the 3.1.x libraries, it fails. Yes, I tried them all up to 3.1.12 I seems to connect to the BT, but fails to download the GUI to the phone. I have seen people posting the same problem on the forum, but I have not seen any solution. Please help!!!

App version 4.13.10,API28
