What to do with ERA crashlogs?

- that looks like an odd era report, no backtrace to an actual line of code?

- you have a fenix 6 pro yourself and it works on your device?

The 3.x,4.x ones could be old FW,

Yes, it works on f6 dev with 6.00 SW.

Backtrace happens on return:

    function getInitialView() {
        //Sys.println("App getInitialView");
        return [ new ProjectXLargeWatchView()];
    }

At least some of these are showing the incorrect FW for the current SDKs.

there was/is a problem where apps can be installed without checking that the devices have the min firmware required, and there's really much you can do about it.  When I get contacted by a user, I suggest they update their firmware.

Hopefully Garmin has fixed this, but I'm not sure.

The permission required error also has the fenix 6 and fenix 6 pro 6.00 listed, I agree that's definitly odd that some of your users experience it while you are not experiencing it.

I'd suggest to open a bug report (for this specific case) and mention that your device doesn't have this problem.

As for the other errors as Jim pointed out many of those are indeed due to incompatible firmware on the user's device. The ideal way to prevent those is when the app store will verify that the user has a firmware on it's device that is adequate. For now you can mention in your app description that user should upgrade their fw if they experience iq crashes.

I guess this is the same issue, as happened long time ago with the positioning and permissions. It wast due to "newer" software did not recognize "old" signature from SDK. All developers had to update the applications using the newer SDK. No other variants. Current solution I see is: I will update using the latest SDK too, see what happen the next days.

As we can see - they cannot fix it due to several reasons for years (I assume not of all we can even imagine). From our, developers, side we can only cross our fingers and pray that customers will update the firmware and do not rate it as one-star. Also there are super-specific devices Rey, Darth Vader, etc, that

Even if I detect the version, that is not suitable - some of the errors happen on early stage  - like function getInitialView().

If you don't want the errors you actually have to downgrade to the 3.1.3 sdk, there's some more info here: https://forums.garmin.com/developer/connect-iq/f/discussion/204433/symbolnotfound-at-return-statement

Doing so of course means that you're dropping the support for devices that were introduced in 3.1.4 or later.
