Unable to Access Clash Royale Account – Verification Code Not Received for Supercell ID

I’m trying to log back into my Clash Royale account, but I'm facing issues with the Supercell ID. When I attempt to connect, it prompts me to enter my Gmail for verification. After entering it, I'm told a code has been sent, yet no code appears in my Gmail inbox. This has left me locked out of my account, which I’ve invested a lot of time in. I don’t understand why this issue is happening, and it’s incredibly frustrating not to be able to access my game. Supercell, please resolve this problem promptly so I can regain access to my Clash Royale account.
