SD card taking ages to mount

[martyjward]

I have a 128GB SD card mounted in my tab S8.4. The SD card is taking ages to mount when I turn the tablet on.

I have re-formated it but no luck.

Any ideas how I can fix this?

According to specs on Amazon, the Tab 8.4 can only use a micro-SD up to 64GB. That might be the problem.
