Hi, for both of you: please specify which type of SD card you are using. Maybe it’s an issue with a specific manufacturer.

Pleas also take a read here and here.

It may in both cases be due to a poor performance for which the phone will not accept the sd card as internal storage which would add up with the built in storage.
