I updated my PCB document based on my schematics and noticed a few nets were missing between components. For example, my current limiting resistor doesn't have a visible net to my LED.
I went back to my schematic and they look visually connected. When I clicked and dragged my LED with my mouse away from its position, I noticed the wires were snapped to the pins (they weren't moving with the LED,) which seems to me like they're not 'connected.'
However, no matter why I do they are not snapping. I have other components where one pin has successfully connected to a wire, but the second pin has not, and the net isn't showing.
Is there something I'm not doing properly? Is it to do with when I created the schematic symbol?
I appreciate any help, first time making a PCB in Altium and couldn't find any clear answer online.
