Phone Presence Sensor

I had an iPhone X added as a presence sensor, got rid of that phone and removed it from the ST app, added my new Galaxy phone as a presence sensor, and now I want to go back to a new iPhone X. (yes I know) Even though this is a different phone with a different device name, I’m getting the error message that says this device is already added as a presence sensor. I have searched but haven’t found a solution. I emailed ST support on Saturday but haven’t gotten a reply. Has anyone found a fix for this issue?

Does it show in IDE? If it does, remove it from there and then add it back from phone.

I don’t see it anywhere in IDE. Just to be sure, where should I be looking? Under Devices?

yes

Had to login a couple of times but finally found it and that fixed the issue. Thank you!
