UPDATE: This issue has now been resolved
As of today, Autopilot is not able to open flight plans properly in iOS 11, we strongly advise users not to upgrade their iOS device as it currently stands.
We do have a fix being uploaded to Apple. It may take a few days for Apple to review and approve our app for distribution in the App Store.
More detailed symptoms of this issue involve map pins not being correctly placed upon opening the Flight Plan. This issue only affects the reading of the plan, if you are currently are on iOS 11, we advise you to not save any changes to your Flight Plan at this time, as it may yield a unexpected result when updating to a newer version of AutoPilot.
If you are reading this after the fact and need a work around, you can make a Flight Plan from scratch to circumvent this issue.
