Oh, God, this is one of those "where do I even start" things, because Roblox is, like, *fractally* fucked. They are terrible at content moderation. A lot of the games are rated incorrectly, so kids can encounter graphic content (sex or violence) out of nowhere --

HARD AGREE.

My mum was as shocked as me. She didn't even know it was a smart stove, her phone never offered to connect.

Right? This feels like a terrible idea. You're not supposed to leave the oven/stove alone while in use!! Why would you EVER need to connect it to a phone??

I don't disagree with you. Part of me wants to hope that it can, but realistically speaking, too much damage has been done to salvage this

Carnicerias, Mercardos, Indian and Asian grocers are a great source of stuff that tastes good and is less expensive than the Kroger monopoly or the Safeway Private Equity Hedge Fund outlets.
But take care with sweet spices & yellow-orange-brown ones. Lead powder is sweet, colorful, cheap, and HEAVY.
