Cannot change settings in e-Manager on e-Golf

[s1m0n]

I've recently bought a 2020 model e-Golf.  In the last week or two, something seems to broken with e-Manager.  I can no longer make any changes in e-Manager.  E.g. selecting an option in a drop down list (max charge current) doesn't change the selected choice etc.  I'm also no longer able to fast change the car

OBDeleven shows these faults after I try to make a setting change in e-Manager:

I've managed to get it all working again. e-Settings screen is fully functional again and I can fast charge again

Here's the things I tried before I got it working:

1. Powered down the car completely, by disconnecting the 12V battery and the high voltage batteries. (Had to recode the 12V battery after this)
2. On the Settings screen of the MIB: factory reset, personalisation reset, then all the other reset options on that screen
3. On the Car Settings screen: all the reset options on that screen

So just another glitch in the matrix
