Apple store apps won't download but have a iCloud symbol
I know my answer might be late for you, but maybe it can help somebody else. I had the SAME frustrating problem with the GOOGLE CHROME APP and I solved it this way:


Go to Settings --> Storage &amp; iCloud Usage
Go to the section that says ICLOUD
Click on Manage Storage
Click on Joana's (Your name) iPhone
At the Backup Options turn off Chrome
Go to the App Store and try to download the app again. Hopefully, it will start downloading! For me this solved the problem.
