If you have diabetes then I recommend uninstalling the app. The app works by frequently entering into Bluetooth scan mode to collect tracing data from other covidsafe users. On some phones this will cause existing connections to drop.https://t.co/DJYiIPGAlo

***Important information for CGM Users***

We have received reports from a number of people with diabetes who have downloaded the Australian Government COVIDSafe app to their smartphone and have experienced connection problems with their continuous glucose monitoring (CGM) apps.

Now, on the topic of @DiabetesAus. It sounds like there's bugs in the CGM apps that they don't alarm for loss of connectivity.

Now, if these apps were opensource we could validate this suspicion easily. @shanselman says it best over at https://t.co/5Mo0ENsx0m

And this varies hugely between phones (e.g. my Pixel 2 can scan, advertise, and talk to my headphones all at the same time). But not all controllers can do everything concurrently, and it's even more complicated if you consider dual-stack (i.e. BT classic concurrently with BLE).
