Weekly Events on Alts

I just finished leveling my second character to 70 and it appears the weekly events are not unlocked for him. Does anyone know why? For example - the siege on dragon and keep exists for my main who finished the entire campaign and is the required renown 5. However - when on my level 70 alt the horn is simple not on the map and I cannot get to the event. Do I really have to play through the entire campaign again on my alt to do these?

Update: I completed the waking shored quest line and it’s STILL not available to me. The only other option is getting to renown 5 on this character despite the fact that when you hover over it - it specifically states it’s an account wide unlock. It certainly appears to not be an account wide unlock.

Update again - got my renown on this guy up to 5 so he would earn it without the account wide achieve and it’s still not available :frowning:
