I agree, not getting good vibes from this product.
- I've submitted 2 requests but no response.
- "In progress" column in Roadmap has been empty for months https://glink.so/kitze/sizzy/roadmap
- Changelogs last updated 2 months ago https://glink.so/kitze/sizzy/changelogs
- Lots of unanswered questions here on Appsumo

He is active on Twitter and answered my question there. There is an annoying bug when you have two tabs with developer tools open, and switching between them always refreshes the dev tools. He mentioned that he hopes to fix it soon, but that was a few months ago. To be honest, I would request a refund if the 60 days were not over. I'm using Firefox again now.
