My Question or Issue

Hello. I cannot see the "Instagram share" option on anywhere. I've tried deleting both apps,clearing cache and data as well as relogging to both apps.

None of it works or brings the share option back.

My sister uses the same premium plan,same phone as well as same versions of both apps but she has the option to share on Instagram,but not me.

I've even tried to factory reset my phone,because I thought that my rooted phone might be causing the problem,but no avail. 

Any help on that?
