We did some digging on the app analytics and it seems that the funky iOS issue is affecting only devices with iOS 12.1 or older. Luckily for us, our minimum is iOS 12 and we have had only 35 users in the past 4 weeks that would be affected by this. Out of ~81k iOS we have in total, those who might encounter this represent a minuscule share of our users. However, that is 35 users too much. Thanks, Apple.
