Instagram usage

Hello! I have a problem with Instagram while posting Stories. I have few accounts, and only for one account repost doesn’t work. However, I tried to sign in to my Instagram account on Android and it works well for all my accounts. Repost doesn’t work only on my Iphones!

What you recommend me to fix this bag?

I updated Instagram few times, ( but it is downloaded from the cloud, because I don’t know how it is delete to refresh story and download it like at first time. Also i restarted my Iphones, but it is still doesn’t work.

Please help, it’s my business account.

Instagram Support service doesn’t request.
