Hi, I have experienced a white screen loading the app in development, but I haven't in production yet.

Also, I am not able to reproduce with your reproduction steps. The app continues to work on my device. If you can determine a consistent reproduction let me know, otherwise I'll keep my eye out.

@sallyFoster Are you running Test Flight, and are you still able to consistently reproduce? If so, can you do me a favor and install 1.23.0, check if you still have the problem, and then check 1.22.0 and see if the problem goes away?

Thanks!

Not sure if it helps, but I think I can reliably reproduce similar symptoms in a different way. I've got an iPhone SE (2016) on iOS 14.7.1 and since TestFlight version 1.23.1 it permanently loads into the described blank screen right after installation. Reinstalling the app didn't help, but a downgrade to 1.22.1 fixed the bug in 2/2 tries. I haven't tested long time stability yet, though.

I think I can't build a voyager app on my "ancient" Mac, but if you need any debug logs I'd be glad to try.

I got this issue several times in 1.23.2 and in 1.24.0 after I installed it in TrollStore and opened. Omw to test 1.22.

I'm running the 1.23.2 (177) TestFlight version and I've been seeing the same issue. After being idle for some time, when I come back I get a completely black screen (dark mode). It happens quite often. Force quitting the app solves it.

I'm on iPhone 12 Pro and iOS 17.1.1, it only started happening recently.

@aeharding No, I am not using test flight. I am using the app store version.

[aeharding]

Thanks everyone for your help.

Because this issue appears to NOT be present in 1.22 and appeared in v1.23, I believe this is related to #913, perhaps due to j3k0/cordova-plugin-purchase#1483.

I have a fix in progress.

[aeharding]

Leaving this open until fix can be confirmed.

i cant reproduce it in 1.24.2 on ios 15.3 iphone se

[aeharding]

Thanks @RocketRide9. I think this is resolved (update is in stores) but because it's so sporadic, please let me know if anyone encounters issues.

iOS 14 iPhone SE (2016) and I couldn't reproduce it within one day of testing. (100 % reproduction rate before, so this is certainly an improvement on my side)

@aeharding The blank screen is still happening in the case that the internet connection is lost and then the user reconnects using a VPN
