Response "BranchResponse" from FlutterBranchSdk.getShortUrl never arrives for some iOS users on sdk version 7.1.0

[mmazurovsky]

Describe the bug We are using flutter_branch_sdk version 7.1.0 and have encountered a strange issue on iOS devices for some of our team members. The method FlutterBranchSdk.getShortUrl fails to generate links for these users, even after updating the app or restarting their devices. One team member resolved the issue by just reinstalling the app, but another is keeping the app unchanged to preserve the test case. After a week of debugging, we've concluded that the method never returns a BranchResponse. The method gets triggered, but nothing happens, and we end up waiting indefinitely for the future to resolve.

To Reproduce Currently we can reproduce the behaviour only on device of our team member (before it was 2 team members but one did reinstallation and the issue dissapered).

Expected behavior Expected to get BranchResponse when calling await on the function.

Mobile (Please complete the following information. remove session if not Mobile):

• Flutter: version: 3.22.2
• flutter_branch_sdk version: 7.1.0
• OS: iOS 17.5.1
• Device: iPhone 14 Pro

Hi @mmazurovsky

Unfortunately, with the information provided, it is impossible to identify the cause of the problem.

If the BranchResponse is not being returned, it is because the plugin did not receive the response from the call in the Branch Native SDK (Android/iOS).

In this scenario, only Branch support can diagnose the problem.

Version 7.1 had some bugs. I suggest updating to the latest version of the plugin that also uses newer versions of the Branch SDK.

After updating the version, check if the problem persists.
