Can confirm, testflight invites still doesn't work :(

Same issue here. Build has a "Testing" green status on app store connect page, but for everyone in the internal testing group the app on the phone just gives the "Currently Unavalilable App Store Connect is unavailable right now. Try again later." error. I found this bit in the docs: "Newly added users in App Store Connect may have to wait up to 24 hours to access App Store Connect for iPhone and iPad". Could anyone confirm that this is really a timings issue and testers should just wait for 24 hours before being able to access the internal test?
