Harshvardhan & Mawra Ignoring Each Other in Posts?

I just noticed that Harshvardhan Rane and Mawra Hocane haven't tagged each other in their posts about Sanam Teri Kasam. Given how much fans love their chemistry, this feels a little unusual. Have they stopped interacting, or is it just a coincidence? Anyone else noticed this? Attaching screenshots—what do you guys think?
