I cant continue the main storyline after receiving the heart of azeroth. I went into chamber of hearts and completed the quest to receive the heart but i didnt get a follow up quest. Logging in and out hasnt fixed it, there is no quest to abandon and i cant even get back into the camber of hearts
After initially receiving the Heart of Azeroth on your first time playing through BfA, there isn’t going to be any immediate follow-on quest. You need to go back to Kul Tiras & progress through the War Campaign and the storyline quests in Tiragarde Sound, Drustvar, and Stormsong Valley (you posted on a Dwarf so I’m assuming you’re asking about an Alliance character). As you quest, you will obtain Artifact Power which will increase the level of your neck piece. When Magni is ready for you to revisit the Chamber of the Heart, there will be a quest waiting for you in Boralus so keep checking back there periodically.
There is no option to even do any of the war campaign, on the characters i leveled previously it showed on the top of the quest log (part 2 of 8 campaign) ect and there is nothing related to it and i cant even access WQ
