Unfortunately, this appears to be another case where the product is supported while the appsumo campaign is running, and then support for the product disappears once the campaign is over.

I reached out to their support over 3 days ago (business days, not weekend) because their authorization system is broken and so I can't even get access to my purchase. Appsumo has also tried to reach out to them on my behalf and no response. After more than 3 days, I finally got a brief response saying "we're working on it" ... that was over a day ago, and nothing since then. I still can't access my purchase and no offer from Headshotly to get this resolved in another way (like manually adding me in).

So, while I haven't been able to actually use the product because it's broken, it's very concerning that they can't even resolve such a critical issue in a reasonable timeframe. You can't even get support for an issue, which doesn't instill much confidence in the product overall.

I really hope that Headshotly will take this criticism and turn things around, as I would love to keep the product ... and I will happily edit my review if they do.
