Update on the Tap detected when gripping issue... the workaround doesn't work. You can disable tracking of one hand in the os settings, but the in-browser app overrides this and accepts pinch to tap from both hands.
There are whispers of an accessibility setting, but I couldn't get a combination to work. This might be viable in the short-term before an AVP app, because I suspect the accessibility changes are lower-level in the stack and can't be overridden by any apps.
PabloSLR Sounds great!
