Hi Lisa. Saw your question and had a few minutes during my volunteering time. Not sure if you found an answer yet. But, I entered your issue into chatgpt and it gave me a handful of possible issues.
chatgpt said you tried the best two options already. The number 1 likely cause is a hardware issue – loose or faulty sd card slot. The internal contacts (tiny metal pins) may be bent or dirty or worn out. The spring mechanism might not be holding the card firmly.
Another possibility is that the SD card may not be fully seating. Fire tablets can be very picky about how the card clicks in. Even a slightly misaligned card may lead to the constant “removed” alerts. chatgpt suggested pressing until you feel a distinct click and reinserting slowly and straight.
The other possibilities include an OS bug, formatting issue or dust in the card slot.
Anyway, I realize that this question was from months ago but I thought I’d look it up in chatgpt to see what I could find. Maybe this will help a customer down the road. And, I learned something new today!
