Summer slowdown plus a pandemic

JustSketchMe has been growing fast and consistently for the past 7 months. It's currently paying 3 salaries and has about 1000 paying subscribers (and about 100,000 free ones).

Growth has slowed down over the past 30 days in a gradual but persistent decline. After a bit of digging I came upon multiple examples of a SaaS slowdown in the summer months (for the Northern hemisphere). I believe that this, coupled with the global recession caused by the coronavirus is behind the slowdown. We've upped our marketing and outreach, so it's certainly something external.

Is anyone else experiencing something similar? Any advice?
