I have connected my Wix store to Facebook, Instagram, Google, and Ebay. There are bugs that need to be killed on each of these platforms.

Hello! I need help fixing bugs on my Wix store that are connected to four different platforms - Facebook, Instagram, Google, and Ebay. The platform with the most bugs is Facebook, and they are affecting the user interface - namely, only some of my products show up on the Facebook store and Instagram. The urgency of this project is immediate, so I need help quickly. Please let me know if you can provide a cost estimate and timeline for addressing these issues. Thank you!
