Can i send you a private email.
You can shell into the system here and get or look at the username file
I have noticed that there are 2 almost identical usernames.
one is denny@atm-hq.com and the other is U_denny@atm-hq.com.
slightly different file size.
Using blynk administrator on ver .18.3 I made a change ( added energy ) just to see if it would take. It actually updated both versions of the user.
Oh. I am wrong. One is
denny@atm-hq.com.Blynk.user and the other one is
u_denny@atm-hq.com.user
