What customer support needs generally take up the most of your time? By rest of your time, are you talking 40 hour weeks? 60 hr weeks? Just trying to understand the time commitment for this amount of MRR
People finding bugs - it's a super flexible tool so lots of edge case bugs. Helping people set up their requests (e.g. no-coders who don't totally understand APIs or DF). Then boring stuff like billing queries/refunds etc.
I probably work 30-40 hours a week total.
