I have recently "upgraded" to the latest 365 version, 12.8.1 from DP11. When I export to pdf the result is that many of the text letters are missing, eg, the word "missing" would appear as m ss n or similar. I am attaching actual cropped sample of a document which converted perfectly from the older version. I have tried this on two different computers with the same result, so there is no question that it is a bug in the 365 version. Unless it can be fixed, this version is rendered useless.
