Hey,
Had this issue at first too.
My r1 will connect to my home mesh mixed network (2.4/5GHz) network but won’t then roam between nodes as I move around the house.
I then set up my Guest network (non-mixed 2.4GHz only) and roaming works fine, been working fine for 2 weeks now.
So I guess it’s the mixed-network roaming it doesn’t like as is happy roaming on 2.4GHz only.

Just to add, I actually got a response very quickly by emailing their support team, maybe that way is easier for them to notice than through the forum…
