Dynamic Link Questions

[Becky Sippert]

Hello!

I'm an iOS developer on an app currently using Firebase Dynamic Links to direct users to install and use our app. We have done some testing on iOS using links with the efr parameter set to both 1 and 0 (which shows the App Preview Page). 

We do not have the pasteboard setting disabled in our app. However, the docs say without the pasteboard, the match type is only guaranteed to be weak. 

My questions are:

1. Is this also true when setting efr to 1, since it bypasses the preview page that uses the pasteboard?

2. Are there any numbers you can share with me about how often these weak matches fail so we can share them with our stakeholders and let them know what our estimated data loss is setting efr to 1?

Thanks,

Becky
