Credentials needs attention - App Store Connect API

Credentials need attention

1. Valid key format

2. The App Store Connect API credentials are not valid or do not have sufficient permissions to list apps. Make sure the key has at least the App Manager role.

3. The App Store Connect API credentials are not valid or do not have sufficient permissions to collect information about your subscriptions. Make sure the key has at least the App Manager role.

I followed these steps:

1. Went to App Store Connect.
2. Under “Users & Access’ > ‘Integrations’ > ‘App Store Connect API’ > ‘Team Keys’, I created a new key with ‘App Manager’ access.
3. Downloaded the P8 key file from App Store Connect and uploaded it to RevenueCat.
4. I’ve also double checked Key ID, Issuer ID and Vendor Number. Everything is correct. But, I’m getting the above error.

Please help me resolve this problem.
