Welcome to the Adobe Express Community!
I tried the same workflow on an Android device, and it worked fine for me! Would you mind checking if the app and the mobile OS are updated to the latest version? Also, ensure you're connected to a stable internet connection. You could also try reinstalling the app to check if that makes any difference.
Still, if you face this issue, you can drop in the device make and model details, installed app & OS version details here. We'll be here to help!
