I noticed I was getting a 400 http error when trying to save my device. Turns out that it didn’t like the “|” in the name but the UI didn’t communicate the error.
Thank you for bringing this issue to our attention. We have been able to reproduce this issue and have logged a case with our development team. In a future update to the portal, we will ensure that unsupported characters are properly detected at the time of saving the device, and that an appropriate warning message is displayed.
