I am using Samsung Music version 188.8.131.52 (on Galaxy S20+) without ads for a while. It is one version older than the most current version which is 184.108.40.206.
Ads on Weather App arrived recently, so irritating! I am starting to look into options. OnePlus has trade-in options for purchasing their phone. They accept multiple Samsung phones, but Galaxy S20 is not one of them currently.
