Although I have disabled the SPAM-filter on my mail server I do not receive the token and the CSV export files sent from the app although the app reports the token and CSV file was sent.
Your community verification mail sent from hello@blynk.cc was delivered in my mailbox within seconds so it does not look @blynk.cc was blacklisted or so.
I use Android 7.1.2 with a fresh installation of Blynk 2.13.3, not on a local server but your cloud.
It is NOT typical, but things do happen. And you would be surprised how many times a simple suggestion was the answer… we all make little mistakes
Have you tried re-sending the Auth code? I have found that it sometimes (but not often) doesn’t go through the first (and sometimes even 2nd) time. But I also use Local Server so that could be compounding the issue.
I have no idea on the CSV export as I haven’t bothered with that myself.
