Well, different ways. You can create Topic here or you can always submit Support Ticket if you have issues.
That said, if you’re referring to not being able to connect, you should be advised that there’s a temporary pause on Uphold for ALL users right now, so nobody can connect/reconnect to Uphold until that’s resolved.
That aside though, there was a bigger issue going on with government and business policies lately. As a result there was a joint decision between Brave, Uphold, and Gemini to narrow down the ability to connect to exchanges to only 19 countries. This means many users around the world won’t be able to link to Uphold or Gemini for the time being and BAT will be stored in your browser. You can see the official notices below:
