Try pressing H.
There are also options on the toolbar (bottom of the screen, press T if you don't see it) for when to show the pins.
That is normal for pins to be hidden, depending on certain preferences.
On the toolbar and in the Toold->Tool Overlay menus you can find the following options:
Auto (only show pins when mouse over image area)
Selected (always show selected pin only)
Press H to toggle the pin on and off.
I never knew I could toggle them lol. They've always appeared for me. The "H" worked! Thank you.
Thank you so much. Pressing "H" worked. Yay!
