There are many potential UX design issues that can impact user experience, but some are more common than others. One common issue is bad navigation. If users can't find what they're looking for, or if the navigation is confusing, that can lead to a frustrating experience. Another common issue is poor search functionality. If users can't find what they're looking for through search, they may give up and go to a competitor's site. Other common UX design issues include forms that are difficult to fill out, content that is hard to read, and pop-ups that are annoying or intrusive. While there are many potential UX design issues that can impact user experience, addressing these common issues can go a long way toward creating a positive experience for users.
