There has been for some time the option to play on “safer seas” where its basically a private server for your party, but you get lesser rewards.

Heck, it should be mandatory. I bought it, I should be able to do whatever I want with it. Its like that for PCs, why not smartphones?

For a single-player game…

I had that issue for a while and it turns out I forgot I had an extension changing my user agent. After I changed it back to default everything worked fine.
