Payment for Self-Improvement SaaS App

Hey all,

I've been trying for months now to find a payment platform for a habit building SaaS product that I'm building (it's still a work in progress, but it's mostly done). Landing page is here: https://rootinify.com. Would love any feedback/suggestions.

I went with Stripe first and they rejected me for some reason and someone reached out and said they'd look in on Indiehackers and just never got back to me.

I reapplied again on Stripe and the same thing happened again.
I tried to go with Paddle, but that didn't work either, does anyone have any advice or suggestions on a payment platform that I could use?

I've been thinking about using either Braintree or PayPal as I haven't tried these two options yet. But it just seems weird why it's so difficult to set this up, I have an LLC set up and everything.

Thanks!
