Just wanted to update. I ordered 3 more cards from Amazon- SanDisk 16g “old style” 90mb read, and they all worked perfectly on the first try. I think I really just somehow got 3 bad cards with the boards from E123. I’ll contact them and let them know they might have a bad batch, dk if it will do anything. Thanks again to everyone who chimed in, for all the help . My sanity thanks you
