What's the most annoying part of running a Shopify store?

I've been wondering if most Shopify store owners struggle with the same things or if it completely depends on the type of store.

If you had to pick just one thing, what part of running your store do you dislike the most?

• Something repetitive?
• Something that wastes a lot of time?
• Something that still feels unnecessarily manual?

Curious to hear what everyone would choose.
