Looking for feedback on balancing product development with customer support as a solo founder?

Reoogle is growing, which is great. But now I'm in a constant tug-of-war. Do I spend the day coding a new feature a bunch of users have requested, or do I answer support emails and help new users get set up? Both feel urgent. I've started batching support to specific hours, but it's still a drain. I used https://reoogle.com to find some old threads on this, but I'd love current advice. For those who've grown a solo business past the initial stage, how did you structure your time between building and supporting? What systems worked?
