I have an issue where I’m pushing out my builds to TestFlight, it goes through. sometimes there’s an error saying that it can’t download but if I try a couple times it goes through. but when I go through and look at my app (That TestFlight says is running the updated version) all I see is the old version

I’ve had an issue with all of my apps. Where I push my build to TestFlight and then the image pops up. I’ve troubleshooted EVERYTHING. My account has no issues on it, no payment or compliance issues. I’ve looked to reddit for advice, one user says they need there app to get approved by apple, i got a couple apps to have there update approve, still the bug persist. Whether the app is on the App Store or a work in progress nothing works.
