Just so disappointed in Amazon for this product issue. I have a 6th generation that is fantastic and wanted to get a second one for my second kid. Decided to wait for 8th gen to come out, it came and all my sd cards get incompatible error message. They all work in my 6th gen and my Samsung tab s. I tried quick and full reformatting in exFAT and NTFS and neither worked. Tried to work with tech support and they had to escalate. Everything they have says it works with exFAT and it definitely does not. 3 different tablets, 3 different SD cards (32gb, 64gb, 128gb) and the 128gb was brand new out of the box from amazon. If you are buying this product and plan to use the SD card to load up media over 4gb (like any movie) DO NOT BUY THIS PRODUCT. Also note that I returned the first one they sent and got a replacement and still didn’t work. I’m not sure if it’s a hardware or software issue. I unfortunately do not have the hours on end to work with amazon tech support (although I did try and do have a ticket number) to get their product to work as it should and their previous version do. Not having exFAT on an SD card expansion slot is mind blowing.
