# ## NOTE: DEPRECATED
# Reason -> Unstable
# The Protobuf object must be provided with an id of the last playlist from the current "page"
# in order to fetch the next one accurately
# (if the id isn't included, entries shift around erratically between pages,
# leading to repetitions and skip overs)
#
# Since it's impossible to produce the appropriate Protobuf without an id being provided by the user,
# it's better to stick to continuation tokens provided by the first request and onward
