Hi, thanks for posting question here.

May I confirm some infomation to understand your situation better?

1. Did you ever try on another phone and is it the same issue? Please share the model and OS of your phones.

2. Can you share the screenshot of any error message when the issue happens?

3. Did you enable Smart Connect?  When the issue happens, your phone is connected to 2.4GHz or 5GHz,  Archer AX23 or  RE650 or RE305?

4.What is the version of your whatsapp? Is it the latest?

Hi,

All the phones in my home are Androids and they all have this issue. I have 2 Samsungs, 1 Pixel and 1 OnePlus. (All models are less than 3 years old)

I do not have a screenshot of the problem, but when I try to call someone it shows on the display that it's connecting.

I have not enabled Smart Connect and the problem happens on both frequencies and when I am connected either of the 3 devices.

My Whatsapp's version is 2.24.13.77, which is the latest version.
