Agree with this, having the iPad apps only support one firmware version is a major pain.
This could be particularly awkward for someone who needs to use their device across multiple systems with different fw versions. But it’s also awkward for the situation Andrew mentioned where band members are using personal iPads and find themselves unable to make monitor changes due to an auto update.
Really the app needs to function across different firmware versions (obviously with new features available to only systems using the correct firmware) or there needs to be an app per breaking release so they can coexist on one device.
