Zerotier slows my MacBook Pro


We are using Zerotier to connect into office servers when offsite. When Zerotier is running, my MacBook slows to a crawl. I’ve fully removed and reinstalled it; it happens again. It slows features like predicted email addresses in Mac Mail, but also seems to slow downloads etc.

I assume I am somehow routing everything through the ZT connection, but … how…?

Any suggestions appreciated
