How can I sync my data between my MacOs laptop and my Android phone using WLAN server ?

I can’t sync the data from my Mac to my android phone using the WLAN server. The steps you indicate (here https://support.1password.com/cs/wlan-server/ and here https://support.1password.com/cs/wlan-server-troubleshooting/) don’t seem to work.
First, as explained, I followed the steps for the Mac, and it works, then for the android part, when opening the welcome page on 1password on Android, there is no WLAN server section but Wi-Fi server. Although my wi-fi is on, it seems that the phone does not recognize the WLAN server. I then tried to create a computer-to-computer network from the Mac and then connect my phone to that local network (as explained in your tutorial). I can create this local network but my phone doesn't see it... Maybe there is a problem with Android and it can't connect to a local network ? Or maybe there is something wrong with computer-to-computer network in MacOs 11.4.
In addition, I precise that I have the last version of Android installed on my phone.

In advance, thank you very much for your help
