There are some big parts identified for this case, and because it is dependency of 3rd party service, we can not do much about it.

But more importantly, I think it is the product itself, the market is probably does not appreciate that much of "customization / personalization" as I thought, in other words, we are probably haven't figured out the best path to get the ideal users yet.

In the other side, free users do not have this issue. We do have free tier which counts for 1/3 of all active users.
