G’day sklose.
So I had a very similar problem getting 2 x XV2-2 to mesh together I went to Cambium support who also initially had the same problem they devised a work around by doing the following.
(A) Changing the country to the U.S.
(B) Downgrading the Firmware to an earlier version
(C) Setting up a special Mesh WiFi between the 2 x XV2-2 units
Not sure if you are just an end user or a partner but if you let me know I’ll try & help you either way ( if you are a partner I will direct you to the Cambium Partner support person who help’ed me )
