@Lusiiky That’s because no new connections to Gemini are allowed unless you’re in the United States. It’s been discussed a lot in different places and announcements made.
Brave has slowly been restricting countries since July and then been adding them again. Support is being restricted as Brave, Gemini, and Uphold work together to implement better security and other updates to their systems. The goal is to have support added to most countries again by the end of the year, but we’ll see how that goes.
So yeah, you won’t be able to connect a new device to Gemini unless you’re in the United States.
