I have a Polo Moda 60 which I have recently got as my first car so excuse my ignorance.
With what I believe is the Midline Cluster from my understanding, please see image of dash:

I also bought a Carista adapter and currently running the 1 month free trial.
I mainly bought it to play around with the MFD, so when I initially connected it about 2 weeks back it said the MFD was disabled even though the display was showing fine in my car.
So I enabled it started to show the Fuel Range display in the top section, which was great as I’d much prefer to see this than the outside temp.
Later on again messing about I “disabled” the MFD through Carista hoping I could cycle through temp and fuel range, it just reverted back to temp.
I do not have the wiper stalk with the buttons unfortunately which I found out later through this forum, is kinda key to cycling displays etc.
Issue is now when I set the MFD to enabled on the app it does shown fuel range anymore. Seems like nothing on the MFD side of things changes, as even tried to change language to German for example and cluster region and none of those changes showed.
Checked to make sure the app wasn’t behaving funny changed some other settings such as enabling horn when locking and that enabled fine so the app is working and the connecting to the phone.
But anything related to instrument isn’t changing for some reason.
Contacted Carista they don’t seems to have a clue, I’ve uninstalled and reinstalled app still any changes made under the instrument section don’t seem to reflect on the car.
Bit stumped as to why, as it seemed to be working on the first use.
Any ideas am I missing something completely obvious here?
Also in regards to the wiper stall with the trip buttons how easy are they to install? If I was to buy a used part, as I’d love to have more control of what shown on the display.
Sorry for long winded post hope it’s clear.
