What browser are you using to access ASC, on which macOS?
same issue here.
These are the configurations I tried:
+ Google Chrome 76.0.3809.87
+ Safari 12.1.2
+ Firefox 68.02
+ Windows 10
+ MacOS 10.13.6
The problem is reproducible in all the projects and all the subscriptions.
When I trace what's happening using the Google Chrome Developer Console, I see this call right after clicking on "View subscription prices":
Request Method: GET
Status Code: 403 (from ServiceWorker)
then it redirects to the home page
