I bought the official raspberry pi touchscreen with RPI -3 case, i installed the OA Pro in my 16G SD card using RPI Imager. I connected ASUS Bluetooth 4.0 Adapter and my old USB sound card (ebay site). Now when I booted PI, touchscreen becomes un-responsive, I could select the checkbox and I am not able to click on Accept button. Now, I FTPied the original RPI config.txt, booted my PI, and configured with license key and connected my phone seems to work fine. Then I renamed the original pi configuration and re-enabled the OA config.txt, again getting the same screen un-responsive issue. I am still trying to locate the issue and I couldn't. Let me know if anyone have any solution. I attached both the config files.
