I mean fair enough, i use this version of Spotify and don't pay them a single cent: https://bestforandroid.com/apk/spotify-premium-mod-apk/
But if I was a paying customer i would be pretty pissed opening Spotify the first time on my 3 week travels and seeing this crap :-O Funnily there isn't even an option to change the location as suggested. Neither in the modded app nor on spotify.com on FF mobile.
Use a different client, or the web player then. This is a settings issue and attempt of them to combat IP switches and account sharing. You're not a paying customer, and I've not had this issue on a paid account before.
Honestly, Spotify kinda sucks anyway. Use something else.
Agreed that Spotify kinda sucks. That is why i am using it the first time towards the end of a 3W trip :-D
With the modded apk and a 10min mail account it is worth the storage on my phone.
Yeah, there are modded clients out there that remove the crap, and dozens of other unofficial clients as well. You have options.
