In the 6 GHz band, PSC's are defined as one of every 4 channels (one per 80 MHz), to speed up scanning. Ch 37, 53, 69, 85, etc.
Operation on any channel is allowed though.
If the AP is operating on a non-PSC channel, WiFiAnalyzer does not see it. Even if the phone is connected to that non-PSC channel.
Testing with WiFiAnalyzer 3.0.6-58G (12-31)
To Reproduce
Steps to reproduce the behavior:
1) Set Wi-Fi 6E Access Point to Channel 73 (a non-PSC channel)
2) Open WiFiAnalyzer channel graph, set to 6 GHz band, and ch 65-93 range.
3) Wait for something to display on the graph.
4) Connect the phone to the AP operating on channel 73.
5) Observe that WiFiAnalyzer still does not display the SSID even while phone is connected to AP on Ch 73.
6) Set Wi-Fi 6E Access Point to Channel 85 (a PSC channel)
7) Observe that WiFiAnalyzer immediately displays the SSID
Expected behavior
WiFiAnalyzer should display SSIDs on any valid 6 GHz channel.

The issue probably is hardware. (AP or phone)
