Maybe Apple typo’d an app id incorrectly for some iOS core app thing in 26.4.2 and the one-character error is this app? I don’t know that anyone’s done a ‘likelihood of collision’ analysis on appstore unique IDs yet. Certainly I could see iOS having a “must be on the device” system set up for apps like Phone and Settings that has a last-ditch of reinstalling it if somehow deleted. Would be especially interesting if some core app that can’t normally be deleted is currently unprotected (back up your device locally first!).
