All but one of my app users are operating in the USA and are using it with no problems. I have one customer in Canada, with four users. They have had problems using the app from the start. However in the last month it will not open for them at all. While they can download the app from the Apple Store to attempt to reinstall, it will not open. Has something changed in the past few months that would cause this to happen?
Canadian Users Can't Open My App
it will not open for them at all.
Can you be more specific about the symptoms? Does it crash on launch? Or does it launch but fail to present a usable UI? If it crashes on launch, please post a crash report here, using the instructions in Posting a Crash Report.
Most problems like this are caused by bugs in how you handle language or region.
There are two official languages in Canada, English and French. Are all Canadians having this problem? Or just Anglophone ones? Or just Francophone ones?
Try configuring a test device with one of these languages and Canada as the region and see if you can reproduce the problem. Specifically, in Settings > General > Language & Region set the Language list to either English (Canada) or Français (Canada), depending on your answer to my language question, and then the Region selection to Canada. Then re-install the app and see if it fails to open.
Note It’s possible that this won’t reproduce the problem, because the problem isn’t triggered by language or region issues. For example, it might be triggered by the app being bought off the Canadian App Store, or triggered by a misbehaviour by some popular Canadian ISP or cellular provider. However, it’s good to start by ruling out language and region.
