Seeing this message “Licence check failed. Please check your license key.” and then DeepAR fails to work. Our app uses iOS sdk version 5.4.1.

I tried v5.6.11 and didn’t see the licence error BUT we can’t upgrade because of this old issue

Ok this is actually (mostly) my own blunder. The license check issue is because our app changed bundle IDs. So I had to delete and configure a new iOS app on the DeepAR developer website.

What threw me off was – for some reason when I _did_ update the iOS SDK to the latest version, the license check seemed to work.
