Happy July 2020. Same problem. I never recieve my email to validate my account or to enable trusted devices. I have attempted to change email to my gmal account, and that doesn't work either. I never recieve the email to validate.
I cannot open a support ticket apparently since I am using ther free version of the software for personal use... but I can't actually use it effectively if I cannot get the validation / trusted devices email. How can I get my email whitelisted so that I can recieve the emails?
