Upbase

I like the software, very streamlined and easy to use.
I am only concern I don't see any interraction and nobody is answering the messages.
Hopefully it won't be any problem otherwise I am scared it would be an issue to get in touch.
I sent a message though the app and tried to post a question in Appsumo, but it seems for nothing. My comments in Appsumo was denied because I already purchased the software.
If i find a way to speak with them I am happy to change the score to 5 tacos but the lack of communication really scare me so I don't feel to give more than 3 tacos right now.
