For text variables for running headers/footers, the default behavior is as described in the help: "If there is no occurrence of the style on the page, the previous occurrence of the applied style is used." Not sure if this is a bug or a feature, but if you are using headers or footers for both sections and subsections, and some sections have subsections and some don't, then you get a header with the name of a subsection many pages back, even though it's not on the page. Having an option to turn off this persistence would make this feature work much better. I've finally had to give up on subsection headers as they just don't work.

Maintain a specific version until a client understands and accepts the update. Surprise changes wastes time and adds frustration. All of a sudden things like Shading pops up in my text and I do not know where it came from and there is nothing in the help system that points me to the very simple method to either change or turn it off. As an example Ctrl + Shift + U adds or removes underlines. In my case the text is highlighted with a random color.

I've been with Adobe and other software providers who never organize and present the very simple procedures within their applications. Do not assume that Adobes customers know everything Adobe knows, it's called dealing with the lowest common denominator. We all have time where things popup that users may have not accomplished a feature.

For those of us deployed in large organisations with indifferent IT departments.
It would be useful in Adobe provided a tool to check which of the (100+?) required Adobe Creative Cloud Network Endpoints were blocked by our firewall.
It is not always clear which endpoint is being blocked.
If Adobe provided a Creative Cloud App or web tool that checked your network and then provided a nice report we could present to the stubborn IT bods (who insist they have whitelisted all 100+ adobe links)

(let not get started on why there have to be so many! Or why therer are regional variations? AWS? but why wasn't this considered and written around appropriately?)

In the background task palette the progress is shown by a growing bar plus a percentage number (double feature for what reason?).

But there is not enough space to display the full file name and the name of the exported file (screenshot 1). Even if you enlarge the palette (screenshot 2) the only change is a bigger progress bar – and no change within displaying the file names.

Yes, I know: the full file names are displayed when I do a mouseover, but expanding the fields of the file names if you expand the whole palette would be a small but smart development.

Remove hyperlink: There is no simple convenient way to remove a hyperlink. When you check, you find, "Edit Hyperlink" or "Go to destination". So, you go to "Edit" and find the hyperlink field, with the only option to delete the hyperlink being the word/letter info of the link that's in the entire field. But then it won't let you do that, saying: "! Invalid Entry". So, you have to reenter the text you had hyperlinked, then delete the text with the hyperlink. Please add a menu line, in both "Text-Hyperlink" and right-mouse-button "Hyperlink" that says and does "Remove Hyperlink", along with "Edit Hyperlink". Thanks!
