I have written a short review already but now, I checked some details.
I ordered 3tier on Aug 2023. It's a little over a year.
If I knew earliesw, that they will be closing down - I could probably take my money back from PayPal presenting Session's correspondence (within 180 days).
I feel ripped off. Many of us will feel the same.
I wrote to AppSumo support as they sometimes have other means to solve the problem.
The whole situation destroys AppSumo presence too...
Honestly?
From now on, I will think 10 times before getting any deal again.
What a pity.
