how do I get an Nissan IITB App to be Trusted on my iPhone 13?

Hello Stratocaster60,

Thank you for reaching out to Apple Support Communities, and we'll be happy to help in any way we can. We understand you're having issues with having a Nissan app trusted by your iPhone. We recommend reaching out to the developer of the app for guidance as they are the best resource to resolve this issue. How to contact an app developer:

"Contact the developer of an iOS, iPadOS, or watchOS app

1. Open the App Store on your iPhone, iPad, or iPod touch.
2. Search for the app, then tap it. If you can't find it, tap the account button  or your photo at the top of the screen, tap Purchased, tap "Not on this [device]," then tap the app.
3. The app's product page appears. Scroll to the Ratings & Reviews section, then tap App Support. If you don't see App Support, make sure that you're signed in with the correct Apple ID.

"

We hope this helps.

Cheers!
