I am trying to fetch all the subscriptions ids of a youtube channel that has 100k+ subscribers. When fetching the first page of results, youtube returns properly the total amount of subscriptions and the next page token.
After a few hundred calls (because you can only fetch 50 results per call), the api doesn't provide anymore the nextPageToken, and the listing stops with only ~20k subscriptions listed.
I tried this on several big youtube channels, and always the same behaviour when I reach around 20k subscriptions listed.
In the documentation I couldn't find anything about any limit on listing subscriptions...
Anybody encountered the same issue ? :-)
Thanks
