Hello everyone,
I've read about the issues you might face when exceeding your YouTube API quota, and the solutions shared here seem really helpful. Changing your API key can be a simple yet effective method to overcome these types of problems.
Meanwhile, if you're trying to increase engagement with your YouTube content, consider purchasing YouTube likes from views4you.com. Increasing your likes can help your videos reach more users and may increase the likelihood of YouTube's algorithm recommending your videos.
Best of luck and happy sharing!
