Email message not showing on Fairphone 2

Hello! Suddenly i am not able to see email messages! I’m getting the emails sent to my phone but its just the Email sender and the title of the email. I can also see the Cc: members but no message!
Any clues??

Which App are you using?
Who is your provider? Maybe they changed something.

Hey Deitmar, Thanks for your reply. I’m on yahoo. So im not really using an app as such…

So you are using the browser to read the mails?

I was… But I have now got the yahoo app so its all fine! Thank you again.
