Apple Developer account error: Maximum number of certificates generated (development)

Question

What do I need to do to add a new developer certificate?

In an Apple Developer account I want to create a new Development certificate.

But I get the error: "Maximum number of certificates generated".

Previously I had 10 development certificates and want to add one more.

I deleted:

• 4 old development certificates (now there are 6 active development certificates);

• 2 production certificates (now there is 1 active production certificate);

• old app IDs;

• old devices;

• old keys.

Also, all of provision profiles (both development and distribution) have active status.

But I still get this error.

I have also run into this issue in the past. From my experience, it restores "empty slots" after 24 hours. If you still have this issue later than that, you may consider contacting Apple support.
