Spotify Antiban Solution Development

I have a data scraping company and I work with music services. Basically, we collect metadata from various accounts that we generate from different countries and reconstruct current trends, genres, tempo, top artists, authors, algorithms, etc., and we sell them B2B to our clients (major record labels) like UNIVERSAL, SONY, and WARNER.
We currently have a problem with Spotify; they are "killing" the accounts, and we are forced each time to generate new ones, wasting unnecessary bandwidth. We have identified that the problem occurs when using the storage credentials (auth_blob) to request the access token (bearer), which lasts 1 hour, so we need to get it often. Then they, based on the quality of the IP, take them down (but we use residential proxies, even Oxylabs, because yes, we have Oxylabs unlocked for streaming services as enterprise clients). We are trying to understand if it’s a fingerprint issue or something else; it seems strange to me that the IPs from the providers are all dead.I have a lot of information about the RE of Spotify (mobile app) so I will definitely simplify the work. Are you able to solve the problem?
