2019 Advanced pauses

Since upgrading to 2019 (Advanced),  I have been noticing intermittent situations where printing will pause for about a minute and then come back.

It gives the impression that the program has locked up but does eventually return.

Then I have a client recently upgraded to 2019 noting that they are locking up and I'm wondering if they might be related.

In both situations, there is a new server being used.

Anyone else noting this?
