Z3 Dual - Data SIM switch broken

I hope someone may be able to assist...

I have observed some strange behaviour from my new Xperia Z3 Dual (D6633) when trying to switch the SIM used for data traffic (from SIM1 to SIM2) - under Dual SIM settings.

When I switch, the change seems to take effect (shows SIM2 handling data), but if you check mobile settings SIM2 remains set to GSM and does not takeover data traffic.

After manually changing SIM2 (under Mobile network settings) to LTE it starts to handle data as expected. SIM1 switches to GSM automatically at this point but remains disabled (marked with a red 'x'). At this stage SIM2 is the only active SIM (handling data and voice).

When reverting back to SIM1 for data you have to follow a similar process (manually making changes to network settings) to restore normal service. SIM2 does revert to GSM only in this case (SIM1 data and voice along with SIM2 voice).

Please can someone advise if this is normal behaviour or if there are any known issues?

Thanks

Andrew

Can't believe I found this. I own a Z5 dual sim phone and experience the same issue now on Android v6. Before updating it to v6 everything was fine and I believe shortly after the update it was still (though can't tell for sure).

In the Dual-Sim Switch App (in settings), both SIM cards are activated.

In the notification bar only one is shown in white (active), the other is shown grey (inactive). Despite this, next to both SIM card symbols I see two symbols displaying the current reception.

I can manually disable the active SIM which would reactive the previously passive one but that's all. No matter with what option I fiddle around with, both SIM cards don't seem to become active-active anymore

Anyone an idea? Any help is highly appreciated.
