Hi there,
my Instagram is working fine on my iPhone and my profile page shows fine on my Mac Google Chrome browser when NOT logged in - but as soon as I log in my profile page says...
Sorry, this page isn't available.
The link you followed may be broken, or the page may have been removed. Go back to Instagram.

Can anyone help? I've tried clearing my cache, reinstalling chrome on my Mac and tried a different Mac too but always the same problem.

Thank you, Stu
