Javascript Wrapper app incompatible with iOS 15?

Thanks for jumping in.  I’m not using syncserver staying on online mode all the time.

Current symptoms:
1. After updating to iOS 15, the app complained and wouldn’t open
2. If I attempt to install a new copy of the app from my website, it immediately gives the same incompatibility message and won’t even let me install it.  Even if I delete the old copy first.  So it isn’t even attempting to run it when it fails.

Here are a couple of thoughts.

Since I’m not using any push notifications, I deleted that product from the Xcode project.  That was always OK in the past.  Do you know if that is OK?

Also there is a section in the Wrapper docs called “Enable App Transport Security”.  “Allow Arbitrary Loads" is a setting that is turned off in the Xcode project, but the docs say Apple might require this to be turned on in the future.  I think it means my app can only connect using https instead of http.  Do you know anything about that setting?
