Hey everybody, recently I've been learning how to use Altium Designer, and there's one error that I can't seem to get rid of. When I try to import changes from my schematic to my PCB, I get loads of unknown pin errors from my three ICs that I have in the schematic. I know I sound like a complete noob, which I honestly guess I am, but this error is keeping me from continuing work on this PCB. Any ideas?

I am a frequent user of altium but a beginner for BGA designing. Can you please help me out. how to create any BGA(stm32 64 pin) footprint. as i have so many issue like i have to download the printprint or can i create it myself.

thank you in advance.
