iOS 10 Notification Weirdness

I’m not sure if this is an issue with SmartThings or iOS 10 but notifications are no longer working properly. I have a SmartApp that will notify me every two minutes that the garage door is open. For some reason, notifications are being “queued” and instead of reminding me to go close the garage door every two minutes, I will suddenly get a notification that says I have “7 new SmartThings notifications.” Which means someone had 15 minutes to walk into my garage and help themselves to my tools, bikes, etc.

Is anyone else experiencing notification issues with iOS 10?

Thanks for any insight anyone can provide.
