Cannot get in same zone with Sync Party levels

Hello,

I cannot play with wife to help her quest.

We are leveling on Dragonflight and we used the sync quest tool but we still cannot do same quest even if we are at same quest level.

Im level 70 and shes level 49 but the group tool tell me she hasnt left the Time Walkers Campaign.

What the point syncing the quest progression if we cannot be in the same zone / instance ?

Is there something i can do to play with her ?

I started a level 50 to help her while she was 42 but doing campain i quickly reached 70 and shes still stick at 49 and now we cannot group any more “in same zone”

We are on same realm same side : Horde
