LATEST UPDATE MAY 6, 2023
The current version of the Tailwind app for iPhones is V2.42. If you have this version of the app, it is now safe to update your iPhone to the latest iOS version available. You can check to see if you have the latest version of the app by going to the app store and searching for "Tailwind Smart". Select it and see if it says "OPEN" or "UPDATE". If it says "OPEN" you have the latest version.
You can also check the version code in the Tailwind app by tapping the top left corner to bring up the main menu. The version code is shown at the bottom of that menu.
Apple developer support has informed us of some undocumented changes implemented by Apple that impact background location tracking, which is necessary for auto-open / close to function. Apparently they are not at liberty to discuss what those changes are, but they did suggest some setting changes within our app to address the issue. Initial testing confirms the issue with iOS 16.4 is resolved. We are are making some necessary additional adjustments to our app and will be releasing the update ASAP.
iOS 16.4 has now been released. If you update to iOS 16.4 before the next Tailwind app update is released, you will definitely break your auto-open feature. We will keep this article updated and we will push a notification through the app once the updated Tailwind app is available. The changes needed are NOT trivial and we are working as fast as we can to implement and test them.
Unfortunately Apple is doing it again :(
Our team has been testing iOS 16.4 beta releases and has reported significant bugs to Apple. We are not the only ones. Other app developers from other companies have been reporting similar problems to Apple.
At this time, we ask that you DO NOT update to iOS 16.4 when it comes out if you use the auto-open / close features of Tailwind as you arrive / leave home. They will stop functioning reliably if you update to iOS 16.4.
If you have already installed the iOS 16.4 public beta you should be able to roll back to iOS 16.3.1 by following these instructions from Apple https://support.apple.com/en-us/HT203282
We hope Apple fixes these bugs before they fully release iOS 16.4. We wanted to get the message out to our customers proactively in case they do not fix them before releasing it.
According to some of the most knowledgeable people in the business of background location tracking, this is "going to break thousands of apps".
You may recall back on iOS 15.0 through 15.2 when Apple broke background location tracking. That one even locked some Tesla owners out of their vehicles.
We will send further notifications through the Tailwind app notifications and we will update this article as we learn more about this situation.
