I updated the PUI firmware to 4.7.0 on the Neo 3 after reading some documentation about testing Pico Link. After upgrading the Metrics Tool overlay does not display in my app.
I have also tried doing a factory reset and the issue remains.
The current version of Metrics Tool does not work with PUI 4.7.0.
The Metrics Tool for PUI 4.7.0 is expected to be released at the end of June.
