iPhone 5s mobile app log in issues

I am unable to log onto Top Eleven on my I-phone 5s. Everytime I log on it advises me

"Facebook is currently experiencing issues. Please try logging in again"

This has been the same since Monday 5th May. Please can you help me?

The bonus of been able to play on my phone makes your game brilliant. Without I may have to leave the game.

Hope you can help

If that isnt it, and you've tried uninstall/reinstall, try contacting Nordeus Support
