It seemed to be working well a few months ago.

I got back into it after purchasing a quite high tiers and now the lead finder, which is the core concept of success.ai, is totally broken for weeks.

I notified the customer service and it seems like I'm the first person to report this and they will have a look.
So either I'm the sole user of this platform or they just have no idea how to make their app work for their core feature.
