Other tips:
The desktop app offers more screen space and settings, and it allows to change audio input and output devices. It is advisable not to use Zoom with audio speakers to avoid feedback. Bluetooth headphones is the best option for output while playing, but you should use the internal microphone of the laptop or the external microphone or audio interface as input device, and not the headset, for improved audio quality. That option is only available in the desktop app. With mobile app you should use the internal microphone of the tablet or the phone.
