Tips for running my Amazon storefront.

our small business is up on Amazon. we had some help getting there with roughly 15 products and variants. setup by an experienced person setting things up but who is now looking to step away.

Would it be very difficult for me to edit the creative and run the store myself? i have experience managing 2 much larger shopify stores. but the amazon admin dashboard looks intense.

your opinion as well as any tips on free educational resources that could help me would greatly appreciate it.

i think the heavy lifting of the initial setup is done, i thought i could possibly make a go at it, at least in the short term.

thanks
