I put the microSD memory card into the slot this morning and it is not recognized. I pulled it out and put it into a USB-A adapter and it worked fine. I tried other Micro SD cards and they were not recognized either. Do I need to send this in for warranty or is there something else I can look at that I haven't tried?

Hello GPDaddy59,
May I have the brand, model, capacity of both of the SN cards?
I will consult more form technical support on this issue.
Thank you.
