With this error, there is a specific channel in your subscriptions that is causing the problem. I'd like to know which channel is causing this problem so that I can look into this further.

I know that this might be a tedious task, but could you please check each channel in your subscriptions and let me know which one(s) is causing the issue? I won't be able to continue looking into this until I know.

Ahhh, I found the culprits:

• 'Porcupine Tree - Topic'
• The Pineapple Thief - Topic'
• 'James Labrie - Topic'
• 'News'

None of these are actual channels - just aggregator channels by YouTube's algorithm! Now I've 'unsubscribed' from these, all is well and without error.

Thanks for your guidance. (Looking forward to a watch later playlist feature :))
