If your app is linked on or after iOS 9.0, you must declare the URL schemes you pass to this method by adding the LSApplicationQueriesSchemes key to your app's Info.plist file. This method always returns false for undeclared schemes, whether or not an appropriate app is installed. Apps linked on or after iOS 15 are limited to a maximum of 50 entries in the LSApplicationQueriesSchemes key. https://developer.apple.com/documentation/uikit/uiapplication/1622952-canopenurl

I'm just wondering if there's any new update on this issue. We're still constantly getting feedback from users that our app crashes at startup.Looking forward to your reply.

We've encountered a rather troublesome crash issue with one of our test machines. After the initial crash, we took the following steps to troubleshoot: we used the same bundle ID but with an empty project to do an overlaid run, yet it still crashed on startup. Then, we deleted and reinstalled the empty project, but unfortunately, it continued to crash during startup. However, after restarting the device, the empty project could be opened normally. This situation is becoming quite critical as we've been continuously receiving feedback from paid users who are unable to open our App, and we've had to deal with numerous refund requests. We sincerely hope to get a prompt response from you as soon as possible so that we can work together to resolve this issue and minimize the impact on our users and business.
