When I first inserted my SD card, it showed a notification with an "options button." I proceeded to format the card as external, portable storage, although the system storage format option was available (a mistake on my part). I later realized this when there was no option to move apps to SD card, as you can on LG devices. So, I went to storage settings, and pressed format, and it did not show the option to format as internal memory. Could anyone help me set this microSD card as internal storage? ***
Please note that this is not a previously asked question. I know that my phone has the ability to set it as internal storage. I have seen the option. Read the entire question.
Insert the SD card into a PC, or connect the phone with the SD card in it to a PC via USB. Next, locate the SD card through "This PC" in file explorer. When you find it, right click it and format it as EXT4 or exFAT. After it is formatted, return the MicroSD card to the phone or unplug the phone and then restart it. It should, in the notifications/alerts dropdown say the SD card is corrupted. Click this notification, and you should now have the option to format it as internal storage after restarting your phone.
