Hi @hurra03,
Thanks for the URL! I just tested your site on an iPhone 4s and have confirmed that only 4 share buttons appear. This is normal behavior if the share buttons don’t all fit in the browser.
There’s two things you can do to work around this:
1.) You can enable the “More Options” button to your set of share buttons. The More Options button will appear regardless of how wide the screen is. This will allow your visitors to select from all of the share services we support. It can be easily enabled when you edit/customize your share button settings by clicking the toggle “Show More Options Button”.
2.) You can also enable Floated Share Buttons for mobile. These work great to display your share buttons, including share buttons exclusive for mobile.
Here’s some more information on how it works and how you can set this up.
Let me know if you have additional questions about this. Happy to help!
Thank you,
Mary Anne
