Problem: My Micro SD cards will not insert into the slot fully. I can turn them over and they push in fully BUT will not lock in place. Upon turning them back to proper direction they seem to catch on the tang that locks them into place and they will not go in all the way. Do I need to perhaps trim the card a bit so it will insert properly or go with another brand of cards????? My current cards are 128gb SanDisk that I bought from Costco. Your opinions are appreciated.
