Hi,
one of the pads under C4 on my Zero4U rev 2 has come away from the PCB.
Looking to glue it down & maybe re-solder the pad or add a mod wire... I'm guessing it's a decoupler for the +5V (for port 4?)? The negative terminal is the one that's floating in the air so I guess it just needs tacking back to a GND somewhere?
Any guidance on where to solder it to - I can't make out any tracks that it might have been connected to, or is the PCB multi-layer & it's just a pad to a GND plane?

Yes, it is indeed.

Exactly.
It seems the GND pad underneath is still there. The simplest way will be just push it down and solder the capacitor's negative terminal to that big pad.
