We are doing letmobile poc for a customer. Samsung and iphone works well, but we are having problems with the other android devices. There are 3 different devices which are moto g, lenovo a7000 and another. The problem is that after setting up the e-mail, all e-mails are downloaded, and we see "preview blocked" on the main window. When we try to read any e-mails, e-mail body seems blank. But, we can see the attachments.
Hybrid mode works well, we see the body.
Is there any known issues with Android 5?
