some clarity on my past post on the subject.....
Galfert I agree that "data archive and logging" is designed by MB not work when using an uncertified SLC SD card. However I was running multiple instances of MB on the same local network. I learned this from experimenting - "testing an RPi3b" using a uncertified SLC SD card.
I downloaded the RPi3b version of the MB image from MB's website. Using RPi Imager, I copied it to a 32GB uncertified card and installed it on my RPi3b. After I learned of my mistake of trying to access MB directly from the RPI. Yes you are correct in that I did NOT access MB directly from the RPI. I did successfully access the MB start-up screen from a browser. At that point I had two separate copies of MB running on my local network. One was an active production copy on my old 3020v3, the other was a trial copy of MB running on the RPi3b. Each had a separate IP address. The trial copy appeared to be fully functional except for the "data archive/logging". I scrolled through the initial set-up screen(s) and the data fields such as Network, Weather Station, Weather Networks were empty. There was also a payment screen in the event I wanted to purchase a second copy.
I repeated the RPi3 experiment this morning - see below:
