We don’t notice any problems with the Standalone behavior like you have mentioned though I can confirm that there is an issue with the settings recall when running in third party apps. This has been lodged with the dev team and will hopefully be resolved soon.
Could you please confirm that you are on the latest version of Scaler 2 iOS? That’s always a good place to start and it might help resolve your issue with the standalone version. Current version is 2.8.1
