Domoticz

I realise this isn't specifically a Z2M support forum but just wondered if anyone had an insight in this. A brief back ground first, my Domoticz inst was up to date but my Z2M was on 1.42 so as i was a bit concerned about the upgrade to 2.X and didn't want half my house to stop working so I first did a full card image, then upgraded to 2.X had a few issues but all sorted. I then did a new clean install on a new Rpi 5 of Trixie 64bit, a new Z2M latest install and a new Domoticz install, then did backups of my previous db's etc and restored them to the new hardware - all working as expected except in Z2M any mains powered device doesn't show it has changed state even though it has. I can for example turn a mains socket on or off in Domoticz and I can also do the same from Z2M by clicking the OFF or ON for the device under the exposes tab but the actual switch between those words in the gui doesn't move, this means no devices show in the ON state in Z2M even if they are.
I also have another test install of latest Domoticz and latest Z2M and this works normally as I'd expect, the only difference between the two installs is my new one is on 64bit Trixie and my test setup is on 32bit Bullseye, I can't see this being the reason but also can't think of any thing else !

Anybody ?

I found the reason and it's very simple, browser is too old. To access my Z2M instance from work I use a virtual machine that I VPN into my home network with, the machine is a windows 7 inst and the version of firefox is 115.29 and says it's up to date, Chrome and Edge are even worse as most of the Z2M page is missing when using those. Looks like I'll have to start using a windows 10 machine
