More details from the Twitter thread: it's iOS 7 and up, and it also works on watchOS 5. In some apps like chrome or opera it isn't a full crash, just a "springboard crash".
I always said iOS 7 was a disaster. iOS 6- opened 8 tabs at most (deleting old tabs) and no one complained. These new youngster oses can not even manage memory in a right way — now with all these GCs no one knows how to do it.
