Problem with a dual nstream

I am having the following issue with a dual nstream network. I upgraded from v5.26 to v6.42.3 and the dual stream link stopped working so I reset to factory defaults everything and reconfigured both end points from scratch. I followed the how to guide as described (https://wiki.mikrotik.com/wiki/Nstreme_dual_Step-by-Step) but nothing works. The nstream seems up and running however no packets are routed from one end to the other.

Here are my ROS configs for both ends:

Any ideas?

In configuration of End2, change

/ip address
add address=1.1.1.2 interface=bridge1 network=1.1.1.0

to

/ip address
add address=1.1.1.2**/24** interface=bridge1 network=1.1.1.0

If it does not help, post also /ip firewall export from both ends.

Sorry about that. This is just a typo error. It actually is 1.1.1.2/24 (I have edited the real IPs/MACs and changed them).

There is no firewall anywhere. This is the whole actual configuration.

The official Mikrotik response to this issue was that nstream dual is no longer supported in latest ROS versions and they have no plans to do so in the future. I hope this may save a few people some time trying to fix a known and broken ROS feature. This broken and obsolete feature should have been documented somewhere that is no longer maintained and should have been removed from ROS. It would save lots of time to many of us.
