Welcome to Meshtastic! Hope you enjoy it! You’re not alone in limited use of the devices. I’m an iOS/Mac user and the android app is much further along in development. I’ve used serial connections, the upcoming meshtastic-client by @sachaw and the CLI tool primarily in using my devices. There’s also the Meshtastic-PyGUI being developed by @zebus.
I believe the TestFlight iOS app is currently only supporting firmware 1.1.50.
If you were using the --host argument, there was a recent device side bug that is fixed in the newest alpha release
I hope this is helpful in the slightest! Let us know anything that’s under documented on meshtastic.org. It’s a work in progress and feedback helps a lot!
