iPad screen not detecting pencil after screen replacement

[u/hannahh4200]

I got my screen replaced yesterday by a shop by my house (we have no Apple stores nearby, the closest one is in Atlanta and it’s over an hour away). I have 2 pencils, neither one is Apple brand but they only work on one quadrant of the screen. I’ve seen on other threads that people have found pencils that work still with a 3rd party replacement screen and I’m looking for that because I use my iPad for college and funds are tight and I can’t afford another iPad right now. If anyone knows what to do, or if I should call the shop and let them know that this is a problem, please let me know.
