ZT -- Internet browsing...

What's needed to route the traffic thru the OPNsense WAN for ZT traffic.

do you mean like when away using your phone with zerotier and route browsing back to the OPNsense's WAN ?
If so try going on the zerotier portal and put in network to route 0.0.0.0/0  via <address of OPNsense on ZT network>

That's 1st thing I did as described, but it's not working on any device. I have also added firewall rules to allow any/any.
I can get to the local resources but not out the net which is odd.

WOW... not sure, must be bug. It's now working.? with no change.

Not quite that simple, you need to set allowDefault=1 on the client side as well to get it to accept a default route.
And it's case-sensitive as well, use the wrong case and it will accept the command it but give you no errors and not work

not sure where I set that on Android app or the client app.

I am presuming you are going based on this link: https://zerotier.atlassian.net/wiki/spaces/SD/pages/7110693/Overriding+Default+Route+Full+Tunnel+Mode
