-My personal workaround is to turn off Personal Hotspot, turn of Wi- Fi, then turn Personal Hotspot back on. This produces a prompt that asks if I want to `Turn on Wi-Fi` or use `Bluetooth and USB only`. Selecting `Turn of Wi-Fi` resolves the issue.
-I’ve been doing this for years. I never thought much of it, until at the end of a recent haircut- My stylist was once again fumbling with her Clover card reader. Usually when this happens, I just pay cash. This time I asked if I could take a look. She explained that the Clover gets internet from her iPhone, but occasionally and inexplicably it disconnects. She said sometimes rebooting the iPhone resolves the issue.
-I showed her my work around, and she sheepishly admitted that she’d probably forget. She came to the US as a refugee from Vietnam- age and language aren’t making this any easier. I ended up using stitched together, marked up screenshots to save PDF instructions for her.
-Until last week it never occurred to me to report this “bug” to Apple. I can’t even remember how I arrived at my workaround.
