AirPods microphone not working in WhatsApp, Viber, and Telegram on iPhone 12 Pro

I have iPhone 12 pro with iOS 18.5 (22F76) and AirPods A2031 (6F21).

Using microphone in my AirPods I am able to record an audio in the Notes app with any combination of the following AirPods' mic settings:

• Automatically Switch AirPods
• Always Left AirPod
• Always Right AirPod

Also, it works fine in Instagram.

But AirPods' microphone does not work in any of the following applications: WhatsApp, Viber, Telegram. All of these applications are updated to the latest versions and have access to the Microphone.

What I have tried:

1. Reset AirPods;
2. Reconnect AirPods to the iPhone;
3. Turn applications' access to Microphone off, reboot iPhone and turn access on again;
4. Change AirPods' mic settings:

• Automatically Switch AirPods
• Always Left AirPod
• Always Right AirPod

Can you please help me to resolve this issue?
