Hi スタジオこんこんPLAY,

To help keep our community safe, we limit some of our more powerful features to channels who have built and maintained a positive channel history or who have provided verification.

As of now, your channel doesn’t have sufficient channel history. It has lost access to advanced features. This may have happened because your channel did not follow our Community Guidelines.

How this impacts your channel

You won’t be able to do things like:

• Get higher daily limits for live streams, Shorts, and video uploads

• Embed live streams

• Pin comments

• Add external links to your video descriptions

How to restore access to advanced features

To restore access, you can:

• Build positive channel history by following our Community Guidelines.

• Provide video or ID verification for quicker access. This may not be available for all channels.

Thanks,
The YouTube team
