Acrobat customers are not aware when a PDF is not compatible to edit
The context of this is that when I was editing a business PDF file, the font suddenly started turning into a gibberish font without me selecting it and it would constantly do so every time I edit this file. Furthermore, this exact issue had never occurred in in the past two years that I have been editing this type of document. This is because it was not compatible as I was later told by the Adobe customer support team (Case number available). As you can understand, this issue that took place can be really infuriating for any paying Adobe customer as it is not known to them why this is happening. This left me trying to figure this out for hours and I couldn’t find the exact article on Adobe help centre. The solution to this is I was told, is to 'Open in Browser' then to save as a new PDF file altogether, as the generic 'Print as PDF' method did not work. The support team also showed me an article on how fix can be made too on the Adobe help centre. The issue with this is that it is not upon the customer to contact the support team to then find a solution to this problem because the customer is already frustrated at that point. I pretty much had to learn this in a difficult manner via Adobe Customer support who helpfully guided me on this.
My suggestion is that customers are to be notified when their PDF is not compatible to edit, and notification absolutely must show clear instructions on how to make this compatible too, in simple easy steps so that the solution can be fixed a matter of seconds.
