When we are going to create a list, it is not possible to click the “CREATE” button to take effect because the mobile's responsive interface was not designed correctly. In addition, when an application has buggy responsiveness, I usually activate the cell phone's native “automatic rotation” feature to see the landscape mode application and better see when there are tables/lists with columns, as is the case of ClickUp, however ClickUp is not activated for landscape mode, if it were, it could solve the problem of creating the list temporarily because the “create” button would appear. Today, as CEO of my company, I use the app much more than the webapp because of the convenience, speed and fluidity of the app on the cell phone. I have the company in the palm of my hand and so I believe that you will be right if you focus more on the mobile application.
