[App][Pro] Philips sleepmapper app, wake up light

My Philips HF3672 cannot connect to the home Wi-Fi, despite trying various methods, the issue remains unresolved. For example, I switched to a 2.4G router and attempted multiple reset operations. However, every time I try to connect it via the iPhone Sleepmapper app, it fails to connect to the home Wi-Fi. Strangely, it can update the clock and sync with the time on my iPhone .
I would appreciate your professional advice, as the main issue for me is to solve the HF3672 connection to the home Wi-Fi.
Additionally, I know that pressing and holding the “Settings” icon allows me to view the system firmware version of the device. My version is “M:29A L:29 W:v v 0:5:9” , and my Sleepmapper version is 3.20.0 .
Thank you for your help!

I am sorry, but that is not something I can help with. Other than to point out the obvious, the 2.4 only wifi, and wpa2 max.
