We recently combined YouTube and YouTube Gaming subscriptions, so any channel you’ve subscribed to in one app will now appear in the other app. By default, subscriptions in the YouTube app will send occasional notifications. You can change your notification settings at any time!
Can you send a report directly from YouTube via the feedback tool: https://goo.gl/ilGA3S ? You can include examples and use the hashtag/keyword #oldsubs to help us locate the report. Thank you!
