Were you ever able to solve this? I have a similar issue; however, this issue is that the list of items is never populated. I click on the “Choose” button and a progress spinner appears, but nothing ever occurs after this.

Did you ever find a solution for this? I am developing my widget now and am having a similar issue with the dynamic options. Thanks.

I actually wrote an article on this topic. You totally can do it (and it works very well). Adding Google Mobile Ads (Admob) to your SwiftUI app in iOS 14.5 https://hrtlabs.medium.com/adding-google-mobile-ads-admob-to-your-swiftui-app-in-ios-14-5-5073a2b99cf9

Did you find any solutions to the performance issues? I am facing similar issues.
