A very quick question that probably has a very quick answer.
About a month or so ago I upgraded from V3 to V3.4 20351 with F9 maps. It all went well and has worked ever since.
I just went to create a USB of the latest version (21020) with F10 maps and it says the install mode is downgrade.
Is this correct and is it safe to continue and use on my car? I used the same laptop and Syn3 as I used for the first upgrade and in the settings it said I was on 20351. I have also used the same USB flash drive that still contained the files from the first upgrade.
