MiroPets needs a browser from 2020 or newer. The one on this device is older than that, so pages load but the buttons on them don't respond - you can't adopt a pet, feed one, or play a game. That's not something you did wrong; it's this browser.
On an iPhone, iPad or iPod touch every browser - Chrome and Firefox included - uses the same engine as Safari, so installing a different browser won't help; only a newer iOS will. Some older devices can't be updated far enough, and there's unfortunately nothing we can do about that one.
