Thanks for reaching out. I'd like to inform you that "Icons" are now included in the "Shapes" tab.
You may refer to this screenshot; though this is from the web app of Creative Cloud Express, it also applies to mobile apps.
Let us know if it makes sense.
Are there any plans to restore the old icons that were available before the "Shapes" update, or are we stuck with the extremely limited library of shapes now? The vast variety of icons that were available was extremely useful to me. Now, very few of the icons I used frequently are available, even with creative searching. This is very frustrating.
"Design assets" was the first thing I tried after realizing hundreds of Icons I was using were either unavailable or hidden behind weird keywords. It is inadequate and unsuitable for my purposes.
