If i go to Email tab and open some sent email with attached pdf invoice then, if i tray open this pdf, then web browser shows PDF source code instead PDF itself.
Firefox, Chrome and Edge same.
At moment this problem seems to be only in Email tab, nowhere else…
If i click with right click on mouse, thist pdf attachemnt and save this pdf to my computer, then all is fine, pdf is correct (screenshot 3 - Save link As…).
(sorry my english)
