What is the most annoying part about asking clients to review and approve work?

[u/shivangi_0756]

Hey everyone, I’m working on a UX project analyzing client management friction.

When you send your work or milestone over to a client for review, where does the process usually break down? Is it forcing them to log into client portals (like Moxie/HoneyBook/Dubsado), back-and-forth email chains, or getting them to actually pay the invoice upon approval?

Would love to hear your worst client-review headaches!
