Hub Mesh Stopped Working

I have two C8 Pros - One in the house and one in my barn. I have all automation running from the house unit. About a week ago, all hub mesh devices quit working on my dashboards. I realized that if I toggled switches, etc. from the house C8, they didn't respond. If I toggle them from the Barn C8, they work perfectly. Anyone encountered this? Any ideas?

Have you tried something simple like rebooting each hub?

What do you see in the hub mesh settings pages of each hub?

Have you confirmed that both hubs are on the same subnet and can see eachother?

Thanks, guys. I ended up tracking this down last night. Turns out one hub was on a different software version than the other. Not sure how that happened, but now that they are both on the same version it is working again.
