Even being a maven, I still do not own a pan. It’s never suited my needs. sadly I don’t think I would be much help to you on this one except for knowledge on SD cards which we have just checked off. I would like to say thank you though for doing the due diligence and looking at the card and debunking that as a possible issue.
Let me hit up my amazing friends and maybe they have some sort of information on this that I am not privy to or have missed. The maven’s do a heck of a lot of reading. @Mavens
