I literally yesterday had to buy my first iphone since the 3G because my wife bought some BLE hardware for her work that won't work properly with her Pixel 3. (It's a set of 12 devices and the Pixel can only connect to six at a time). The manufacturer won't even list Android devices they claim to have tested it with.

Our management kept asking us to fix these issues with software. We tried things like transparently rebooting our BT module and prompting the user to do common fixes (e.g., "turn your phone off and on again") but most of the time these wouldn't work, unsurprisingly.
