Can't re-enable COVID-19 exposure notifications or tracking
I live in London, where there was no COVID-19 exposure notification app until today. To see how the technology works in other jurisdictions, I installed Beat COVID Gibraltar on 18th June 2020 and COVID Tracker Ireland on 6th July 2020. Although both apps worked fine and were tracking exposure, I couldn't do much with the apps, given that nobody around me was using apps from Gibraltar or Ireland. Instead of deleting the apps, I disabled exposure notifications in iOS.
The option to re-enable exposure notifications (or possibly a slightly different previous phrase) has disappeared in iOS 14 or probably in an earlier iOS version such as 13.6.1. After I installed England's NHS COVID-19 today, 24th September 2020, and deleted the Gibraltar and Ireland apps, the England app told me "Unfortunately, you can't run this app. This could be due to: A restriction in your settings; Another app on your phone using the same technology and stopping this app from working".
Obviously it's not the latter reason, because I deleted the Gibraltar and Ireland apps, so it must be my earlier disabling of exposure tracking that is causing the issue.
I get similar issues if I install the Ireland, Scotland or Gibraltar apps (on their own without the other apps). The other jurisdictions' apps give more explicit error messages. For example:
- The Ireland app tells me "Service is not active. To update your permission settings, go to your device's app settings".
- The Scotland app tells me "Tracing is not active at the moment but you can fix this later" and "Exposure Notifications are required. 1. Go to device Settings. 2. Switch on COVID-19 Exposure Notifications. 3. Re-open this app".
- The Gibraltar app tells me "Exposure notifications are required. 1. Press 'Go to app settings'. 2. Switch on COVID19 Exposure Notifications. 3. Re-open this app, and it will be activated".
If I go into Settings, Exposure Notifications, Turn On Exposure Notifications, it just takes me to a country selection page, where it prompts me to download the app for my country or region, which I have already done. It doesn't re-enable exposure notifications, and this remains off, even if I re-download and re-install each app. There seems to be a hidden setting pre-iOS14 or pre-iOS13.6.1 that I can't undo.
I spoke to Apple Support, who focussed on irrelevant matters such as wifi profiles. They also wanted me to "reset all settings", which would permanently delete a huge amount of my data such as hundreds of wifi passwords (with no way of restoring the data), and they wanted me to back up and restore the iPhone, which is extremely onerous with little prospect of success.
Therefore how do I re-renable exposure notifications or exposure tracking?
