Timeline progress aberration in the iOS app

I was listening with the iPad as the user interface, but had switched over to Kindle for a while. IOS multitasking. When I switched back to Roon, apparently the Roon app knew it was way behind. But instead of jumping to the current track and showing timeline progress as normal, it went through all the intervening tracks but moved the timeline super fast. Perhaps 60X faster, a minute per second, roughly. When it caught up, it proceeded as normal.

Recently updated the iPad to iOS 9. Haven’t seen the behavior before, even though multitasking is common. But I can’t swear it is new, I don’t watch the timeline much.

Not really important, but looks weird.

I’ve seen the same thing happen a few times when taking the ipad out of “sleep” mode and going back to Roon.
