Everyone is having this problem because App Store Connect is a nightmare.
Not really... I had 6 or 7 iOS software titles with subscription plans last year alone. It's only new comers who are having problems. People don't come here every time their app with subscriptions are accepted. And only those new people contact Apple Support and file an expedite request several times just for a single submission.
