Hi Fireblocks team,

I registered [from here](https://www.fireblocks.com/developer-sandbox-sign-up) for the Developer Sandbox and accepted the Testnet Workspace License Agreement, but I have not received the Sandbox invite link.

I can access [community](https://community.fireblocks.com/), but login to [Sandbox](https://sandbox.fireblocks.io/v2/) fails with:

> “The credentials you entered are invalid.”

Could you please check my Sandbox workspace provisioning and resend the invite link?

Email: _tpn02\_havanbien@r-techno.holdings_

Thanks.

Same problem. Did you ever find a solution?
