I have a mixed H/W version M9 Plus mess network - 2 units are V1 and 3 units are V2.

I just reset the whole system from Acces Point mode to router mode and the network became unstable.

After digging in and long chats with support - I cannot get the V2's to the latest firmware.  The V2 are staying on a 2019 version.

When I update via the IOS app or the WEB-UI - it says I'm "Up to date", but really it's not.

Anyone else solve this.  I have tried a V1 and a V2 as the Main DECO.  Same result.
