Hi, I just noticed that HiFi has been finally integrated into Premium subscription here in Poland. But since I'm still paying for my 'old' Premium subscription, I have no access to HiFi yet.

Back when HiFi was a separate offer, you could upgrade even if the previous subscription hadn't come to an end yet. Now you obviously can't because both offers have merged into one.

So what should I do now to have access to HiFi? Wait until the end of my current subscription and then subscribe to the new offer? Is there a faster way to upgrade?
