Interesting. The same thing happened to me. Was offered a refund (graciously, as I had forgotten to cancel the subscription). And after thanking them and agreeing to the refund, was promptly ignored!
I remember rowy from a while ago. It said then that other databases (aside from Firestore) are coming soon. Any news on that? I'm looking for a Postgres frontend.
Demo uses postgres compiled for WASM so demo runs on an actual postgres db.
