Zoom phone app locks up on incoming calls. Unable to swipe to answer using my iPhone 13

[JimW]

Incoming calls to the Zoom app on my iPhone sometimes lock up when I try to answer them. Sometimes it works fine, but other times I am unable to answer them.  

When I try to slide the answer button over, it just does not react. Its frozen and I cant access the call. The phone continues to ring as if I ignored it. This is happening in and out of the office on network and wi-fi as well.

I am a delegate for another user in our enterprise system. This is not a call que or any other complex application.

Hopefully someone can assist, thanks.
