We recently upgraded our site from I think 2.2.6 but it may have been 2.2.5 to 2.2.7p1. Since then one of our admins (and possibly other community users) have been having missing the editor text both when accessing the site using an older iPad. Our admin has an older iPad 3rd gen running IOS 9.3.6. As you can see below from the screen shot the entire editor box is missing. I had him clear all Safari history and website data and it did not make a difference. I had him then login here and he is seeing the exact same problem on the XF office site. I then had him login to our test XF site which I have not patched in a while and is still running 2.2.4 and it still works perfectly fine for him there. It seems to be some sort of bug in the 2.2.7 or 2.2.7p1 patch that broke the text editor in older IOS devices. Please let me know what other data you need to look into this problem.
