I would kindly ask for the feature to show the CPU Temperature on GL.iNet Mobile app (Android) to be considered, same as we get it on the website version. I am not sure the iPhone version of the App has this feature or not.
We have reproduced the issue on MT6000 v4.8.3 and will confirm with the R&D team.
Your version appears to be op24? Please verify this under System - Upgrade so we can request the R&D team to investigate accordingly.
