This issue started happening with me as well after the latest update for the app. I noticed a change when my morning syn went from 5 seconds, to almost a minute. Long story short, to resolve this issue I went into the app, clicked the add device link, and went through the steps of setting up the device as if it were the first time.
The app will recognize that you already have an Ionic setup and will as you if you want to replace it with the new device you're setting up. Click yes, follow the same steps as when you first setup the device and once complete, the device should be synced.
I've tried syncing several time since I did this and it seems to be working as normal; ie recognizing the device, syncing within 5 seconds again.
I hope this helps.
