Minimize Pop-ups
I've seen a lot of posts on this topic, however, I want to add some specifics to better quantify the issue. Major pop-ups that routinely affect my work are "do you want to make this a trusted document," "enable all features," new feature announcements such as "adobe has a new look," "do you want to make adobe the default program," and more that I might not be remembering right now.
As far as the "do you want to make this a trusted document" and "enable all features" prompts, I'm sure there's a reason these pop-ups exists. That being said, regardless of which option I click to either of these prompts, I can still do what I need with the document. What does that mean? For my purposes, these options are inconsequential yet I get prompted to select them for every document I open. Sometimes I have to process 20 documents at a time. Some pop-ups can even stop me from opening other documents until I acknowledge them. My advice, for the average user, adjust these options automatically to the most secure unless they click on something which requires the document to be "trusted" or for all features to be enabled. I still don't know what either of these prompts actually do, so, as far as my daily uses this can probably be preset.
To address announcement pop-ups such as "adobe has a new look," I completely understand why your business needs to advertise its innovations in order to maintain an edge over any competitors. However, for the average user, I believe your product is relied upon for being a consistent and reliable method for opening, reviewing, and editing documents. The average user already knows what buttons to interact with to accomplish what they want even before opening adobe acrobat. For those that need help or want to review customization options, these features should be located in a help sections that only opens when prompted.
Finally, to address "do you want to make adobe a default program" and any other first-time opening adobe prompts, I have some unique advice. My organization is pretty large and probably owns an expensive adobe license. However, at my work, there are numerous instances where we are logging into computers and virtual machines which do not save our user profile. These means, of course, that each time I open adobe acrobat in a session, I am greeted with all of the "first time opening adobe acrobat" prompts. I can't remember specifically what all of them are, but I believe they are about 2 or 3. On slow loading computers or virtual machines with limited bandwidth, this minor inconvenience can often cost minutes. Having that been said, I've noticed streamlining of the "do you want to make this a default product" prompt. It's a lot more intuitive on how to do it, however, I think it should be something accessed in the "help" section rather than a pop-up that comes up when the product is first loaded, for the aforementioned reasons.
Hopefully this advice is constructive. I hope to see adobe maintain dominance as there are still some features that microsoft edge is getting completely wrong in their pdf viewing application, but I want to make clear the time that some of these pop-up features are costing adobe's customers.
