Cannot use the app on iOS 14 – myGMC Review

Here is the error: “ The connection between this app and the myGMC service is being unexpectedly rerouted by a 3rd party process and has been discontinued. This could be the result of a legitimate network setting on your device, a temporary change on the myGMC service or malware on your device. If the issue persists, please uninstall this app and install the latest version from the app store.”
