When I got Android 6 on my phone tried out the use memory card as internal storage, I switched back to using memory card as external storage as I could not access it with ESFile Explorer, also cannot take the card out and use it on my laptop.

Even using my memory card as external Android 6 seemed to add some restrictions that weren't there before, so Android 6 for me made using my memory card worse than Android 5 whichever way I configured it.

Windows doesn't have native support for ext4 file system and even with some apps it's only read-only and often buggy. But it's weird that even on your phone there was no access for local apps. Maybe apps had to do some update?

What are those additional problem you've mentioned?
