We have some good news and some bad news. The good news is that we were still able to bring back the support for iOS 7 in version 1.9.2. The bad news is that this is only a temporary fix, and unfortunately we will be forced to drop the support for iOS 7 in one of the future updates.
We'd love to keep supporting older devices, but some of the 3rd party libraries we depend on have decided to drop the support for iOS 7. This change mostly affects iPhone 4 users, because Apple has stopped providing iOS updates for those devices since 2016.
We realize that this is a disappointment for the (small amount of) users affected, and we sincerely apologise for the inconvenience.
