Thanks, Dennis. Yes, I did that exact procedure. After clicking "re-install" there's another screen where I was asked to re-confirm which package to install (screenshot below). I selected the "Update" option on the perpetual license. I received a successful install confirmation. I then received a successful connection notification from UDMobile for ecobee. Then, after about 90 seconds, I get a disconnect notification from UDMobile. Checking the Polyglot dashboard, it shows me disconnected. There are also 2 messages: one saying the install was successful, the other instructing me how to apply the PIN on the ecobee website (which I did NOT do this time). On previous attempts, I did go and update the PIN with the new one in the message as quickly as I could (i.e. before the disconnnect notice) but that didn't work, either.
