Frustrated, mostly because you left me on my own
You really expect me to navigate all invoicing and payments without much help? The sign-up process might be straightforward, but after that, it's like you expect users to just know how to handle billing questions on their own. I had to figure out multiple steps by trial, searching for how to update payment info and deal with invoice formats. Only the automatic invoicing was consistent and fine, I’ll give you that. But the lack of clear guidance on payment adjustments means I spent way more time than should be necessary just to stay current. The whole thing was frustrating enough that I’m probably going to be extra cautious with renewing unless you improve the clarity here.
