My bot has stopped receiving notifications chat_member, my_chat_member, chat_join_reuest

Hello, I'm experiencing a similar issue: GitHub Issue #480. Updates are not being received in the update channel when a user joins a group (more specifically, updates are not received every time, though sometimes they do come through). I'm using the library version v5.5.1.

Here is the getWebhookInfo response:

{"ok":true,"result":{"url":"https://.....","has_custom_certificate":true,"pending_update_count":0,"max_connections":70,"ip_address":".....","allowed_updates":["message","callback_query","chat_member","chat_join_request"]}}

I tried to search for information myself and realized that I'm not the only one facing this issue. Maybe someone has a solution or a workaround?
