The 'Update' object sometimes does not have an attribute 'reply_to_message' in private messages

Question

I've encountered a situation in Telegram where my bot doesn't receive reply_to_message in private messages when a user replies to the bot's message. I'd like to understand why this is happening and how it can be resolved. The issue isn't consistent; for example, a reply to the bot in the morning might contain reply_to_message, but an hour later, it may not. Nothing changes on the user's side during this time.

Details:

I'm using a webhook on a URL.
The issue only occurs in private messages, not in group chats.
The bot has all the necessary permissions and is configured correctly.
Could you provide information on how to ensure reply_to_message is received in such cases? There might be some privacy settings or specific conditions I'm not aware of.

Thank you for your assistance!
