support documentation indicates that engineers are actively addressing the freezes and crashes encountered by Android users. As of this writing, there is no official timeline available for the release of a fix, and with a lack of clear reasoning for this issue, users have limited options for attempting a self-resolution.
It seems, at least according to the support page, that the issue might be somehow linked to connections with certain Wi-Fi networks. Therefore, if you are experiencing an unresponsive Spotify application, consider disconnecting from Wi-Fi to check if that alleviates the issue.
