GL-MT1300 microSD

I was using a microSD card to extend the OVERLAY with block-mount
However, the microSD mount information and the link to the microSD disappeared with the update, but I checked the overlay from luci → System → Mount point, but even after rebooting, the overlay is not extended at all.
If possible, I would like it to be mounted automatically from GLiNET’s UI instead of using luci (I would rather have a larger Flash ROM than bother with microSD).
