For paid membership sites owners - what are your most urgent and pressing problems?

Hello everyone. This question is for anyone who owns a paid membership website: where you charge each month a quote to your users.

Maybe for a niche community you manage.
Maybe for some recurring product purchase.
Maybe for some kind of training website.
Maybe you have a premium newsletter.

Over the years, I helped all kinds of clients in this "niche" as a web dev and designer. Some of them had 2K in MRR. Some had over $70,000K in MRR.

I'm trying to create a service for you. Problem is, it's hard for me to truly understand what problem I should help solving.

Is there any particular problem that you're dealing with constantly, month to month? Something that, if solved, can help you save time or increase your revenue?

I would love to hear about your experience with your business. Maybe you're also using some services that you pay monthly and you aren't happy about.

Any idea is welcome. And I open to help you too if there's any problem where you need external feedback.
