Thanks for testing and reporting this! The QR endpoint itself works fine directly (POST /qr with {"text":"hello","format":"png"}), but sounds like the UI form may have an issue on mobile.
Can you tell me what happens – does the button just not respond, or do you get an error? I'll look into it now and push a fix if there's a mobile layout bug.
In the meantime, the raw API endpoint should work fine from any HTTP client.
