How can I fix Telegram notification problems on AirPods Pro 2?

AirPods Pro 2 do not announce notifications from some users in Telegram even though all settings are enabled

What I have checked

Announce Notifications is enabled in iOS and allowed for Telegram

Notifications for personal messages are enabled in Telegram

Notifications appear on the screen but are not announced through the AirPods

If I send a message to myself from another account the notification is announced

Notifications from other users appear on the screen but are not announced

I cleared the Telegram cache reinstalled the app and updated both iOS and Telegram to the latest versions

Checked Focus Mode Do Not Disturb and Telegram notification settings in iOS

Apple Watch is connected but disabling it did not help

I reset my AirPods Pro 2 to factory settings but the issue persists
