preview deletes all text after markup
For some pdf files after I highlight even one word or add some text using the markup tools when I closes and open my file again all the underlieng text is gone and just the markup remains. THis makes preview unreliable to use and it means I need to keep backups of all files I decide to mark up. Is there a fix for this.
I am still on Mnterey and wanted to avoid upgrading until I have finished teaching.
I saw soneone had posted about this a year ago but that one has been closed off without any resolution. Has anyone found a fix for this problem?
