Oh no, I’m so sorry for that. I’ll make sure to add this to our internal bug tracker (because that’s obviously not what the “Return All” option should do).
Until then, you could use their API which accepts pagination parameters. An example workflow connecting directly to their API can be found here: Error 413 on spotify - #15 by MutedJam
Pagination itself would need to be handled by you, an example workflow is available here: HTTP Request : Looping over REST JSON paginated results - #2 by jan
Hope this provides some pointers!
