Bug with iOS 9

Great app, have used it for some time now including on my watch.
However, have noticed that after iOS 9 update, the spotlight search to find this app on my phone is unable to find it installed on the phone. This may very well be a bug in the newly released iOS 9, but I am able to find other apps. I have a lot of apps on my phone, so the convenience of doing a quick search and selecting that way is helpful.
