Unable to Access My D&D Beyond Character on My Laptop

I'm having trouble accessing my D&D Beyond character on my laptop.

I originally created my character using the D&D Beyond iPhone app, and I can still access and play the character on my phone.

However, when I sign into D&D Beyond through a web browser, it takes me to a different account.

Here are the details:

• iPhone app username: j4n72yj7mp

• Website username: dzjyv9yd2n

• Character name: Thud Hugginstone

• Character: Level 1 Goliath Barbarian

• Campaign: Rise of Tiamat

My Apple sign-in appears to be linked to the website account, but my character is only showing in the iPhone app.

I'm currently playing this character in an active campaign, so I don't want to lose the character, its progress, or its campaign membership.

I've already exported a PDF backup of my character sheet.

Could you please help me identify the correct account and access my existing character on my laptop without deleting, unlinking, or changing anything that could affect my character?

Thank you for your help!
