USPS Mobile Ap won’t launch

I cannot open USPS informed mail mobile ap or the USPS tracking site. I am using ap and Brave on my iPhone 14Pro X phone. I get “you do not have permissions “ error mssg. I have used my ap regularly and it worked. Today, not at all.

To clarify, you’re talking about the actual app itself (downloaded from the app store)? If so, Brave should not have any affect on this behavior.
