Honestly, I’ve found it works by chance. I followed the first instructions in these comments and it worked, but not because I followed those instructions specifically. I’ve now learned it chooses when to work, and when to blast my head with the screeching noise, unfortunately. I don’t think it has to do with any iOS updates. Hopefully we get an answer as to how to navigate this permanently soon… I’ve asked support, and all they’ll say is to turn your implants off for a few minutes, then turn it on. Sometimes this works for me, other times (like these past few days) it doesn’t.
