We integrated the Spotify Web API into our system. For approx 2 months everything was working fine until last week.
I see a lot of errors on the calls we do. E.g Get user's available devices api call give sometimes the response code 403 (Forbidden). Approx 10% of those calls result in this error response. 90% goes well.
This was not the case until a week ago.
Is there any reason for this?
I don't think the quota is exceeded. Our App Status is showing: "Granted quota extension"
