I used credit karma taxes for a few years and it was pretty seamless so trusted their transition to cashapp. There was a delay where only a few states were available; I was willing to wait until my state (MA) was accepting. However now when I try to input my health insurance coverage I get message "403 forbidden" and cannot complete my return. I will have to use another service as I am under many time constraints this year and can't afford to wait for cash app to work out endless kinks.
