What happened to Rob?

3 days ago Yonaka posted a new photo with just Theresa, Alex and George, leaving many fans wondering; where is Rob?

He's no longer on their Instagram bio, nor can I find his Instagram account, AND all of Yonaka's previous posts have been deleted. Could it be that Rob has suddenly and officially left? 😥 I'm really hoping for an update soon but if anyone else has managed to come across a photo or article that might give some insight please link it here!

If Rob is gone, will they be seeking a replacement? Where did he go, is he well? Did they all fall out? Was there another opportunity for him? Why have they deleted all traces of him from Insta? So many questions!
