Weird instagram update problem

Hi guys!
Actually I have a little problem.
I have 3 instagram accounts, everytime instagram rolls out a new update I receive them just for 2 accounts. Not for my main account. For my main account, I have to wait some weeks until I can use the new features. How is this even possible? Any solutions?

It's all server based. So imagine they update some servers but one where your other account is on won't update automatically and needs an engineer to push it through. Hence a delay.
