Certificate problems - RSA cert not being issued


I’m trying to setup a new certificate and I’m having some issues. The first time I tried the verification completed almost immediately but no certificate was issued and the domain didn’t work. After about 30 minutes I deleted the certificate and tried again. This time, the ECDSA cert was issued promptly but the RSA certificate still isn’t there.

Is this the expected behavior? Also, is it safe for a site to go live before the RSA cert is issued? Are there browsers or other clients that will fail to connect with just the ECDSA cert?
