It is quite normal that you would like to check out a product’s free version first before you would decide if you would like to purchase it in the future or not. This time, you may be satisfied with all of the features that you are getting from Adobe Cloud Storage, but you are wondering how you can upgrade to a more premium version so that you can access more apps and features. Look for the cloud icon that can be found in the upper-right corner of the app.
You can click on Files then select Upgrade. Choose the type of upgrade that you would like to do. You will be given options on what upgrade you would like to buy. You will be required to enter your email. Select your payment method and complete the purchase of the upgrade. After some time, you will be able to use the upgraded version of this software.
