I tried logging into dnd beyond with my twitch account but it made me a new account. It is only doing this on my computer. dnd beyond on my phone is completely fine. I cannot access my sheet on my computer and am having trouble navigating my sheet on my phone.

Do you log in on your phone using a different method, such as Apple or Google?

No, I log into D&D beyond on both devices through twitch
