I have a 5 GHZ 40 MHZ B/W PtP link with another station.
After upgrading my station to 4.26.7.0 we could no longer link. The other station did not upgrade and remained on 4.26.1.0
This morning I reverted back to 4.26.1.0 and the link was reestablished. I'm using a Ubiquiti LiteBeam 5AC LR and the other station is using a Ubiquiti PowerBeam 5AC 400 / Gen2
We didn't try upgrading both stations to 4.26.7.0
I have two other nodes running 4.26.7.0 with PtP 20 MHZ B/W links to other stations that work. It appears just the 40 MHZ B/W has the problem.
After making changes, the GUI doesn't change back to the default view after clicking on 'Logout' and requires deleting Windows history to update.

In my case the node rejected taking it backwards to 4.26.1.0 so it's now waiting for a complete reflash.

I see this as an issue ... why would a station that had a stable connection to another station have to be rebooted if the remote station updated to 4.26.7.0?
