Must have Amazon FBA experience

I’ll ask you to list a product and get it approved to be listed. 1) I encounter barriers related to the UPC code though I bought a legit one on GS1. You may need to troubleshoot with Amazon seller support for this. 2) I also have a hard time getting my product photos approved though I have put my brand name on there. 3) I may also need your help with brand registry. In your cover letter, please explain how you plan to help me with these and your experiences with these exact issues. Thanks!
