[CA] WiFi issue with Dragonfly 7 Pro

I am unable to fully connect via WiFi to my Dragonfly 7 Pro with my Google Pixel 2 cell phone and WiFish App. However, I am able to connect via the WiFish App on my tablet.

My cell phone Android software is v8.10. The tablet Android software is v5.0.2. My Dragonfly 7 Pro operating software is v.12.20. What can be done to ensure that I am able to connect via WiFi to my Dragonfly 7 Pro? This lack of WiFi connection also persists with my Navionics+ Android boating App.

Your expeditious response will be greatly appreciated.
