I connected my Braved Destop Browser to Gemini and it went well only missing maybe 15-20 BAT.
I connected my Brave browser on my android phone and it connected but the separate Bat around 48-50 from the desktop disappeared and it just shows me the amount I earned on my desktop browser. Why did my 50 android bat vanish?
When you connect a new device to Gemini or Uphold, the BAT gets removed from the browser and is sent to the custodial partner. Usually this happens within a few hours but can take a day or two depending on the amount and all.
No amounts should be missing. The only thing reduced would be if you not disabled Auto-Contribute and/or if you’ve chosen to tip anyone.
I don’t know when you linked your devices to Gemini, but I’d say if it doesn’t appear within the next 24 hours, your best solution would be to create a Rewards Support Ticket at https://support.brave.com/hc/en-us/requests/new?ticket_form_id=360001302431 and make sure you provide your Rewards ID from all devices and the email associated with your Gemini account, so they can investigate with you.
