If I make text center justified and save the file it is opening back up left justified.
Please tell us some details of what you want to do.
When I re open the file I want the text to be center justified still and not change to left justified.
Which version of Illustrator are you using? What operating system?
Also, can you share a sample Illustrator file (.ai)?
All the latest version up to date windows 10 and checked for update on illustrator. If you give me an email I can send you a video showing you how it doesn't save.
If you are going to share a sample file or a video that may explain the issue, it is recommended to make it publicly available, so all contributors in this forum may take a look at it.
