App Store Connect super slow and existing IAPs disappear

I'm trying to add offer codes to our current subscription item. After a long loading I found the In-App Purchases section was empty, couldn't find any of existing subscriptions.

No luck with Subscriptions -> Subscription Group too.

It has been like this for several hours. Is this a server issue?

It looks like the same problem I'm having since yesterday. See here: forum thread. There might be some problems with IAP in App Store Connect.

I can’t redeem gift codes. In the App Store the “enter code manually” interface won’t open. In the in app interface, valid codes throw an error. Any one else experiencing the same?
