On iOS, get a clear error message if the application is not compatible

Several users with old iPhones find themselves blocked in their usage because their version of Safari is too outdated.

It would be necessary to either:

1. Fix the issue, if it's a bug.

2. Or have a clear error page indicating that the browser being used is not supported and suggest using an alternative browser such as Firefox or Chrome.
