In regard to the config being lost after upgrade, this is something that is expected. When the firmware updates a major version, it deletes the EEPROM and this is done since the layout is no longer compatible with the new one and resources needed to convert between all various firmware jumps could get quite complex.
Instead, we allow the app to export and import the config, as you did.
What do you mean you had to configure the parameters before the program became visible?
Thanks for the feedback!
