Ps4 application not found?

If I want to download my ps4 on the library already bought a game I "content not found" and I will be asked if I want to look for the application in the store, but the store shows me the game as a bought and the Button "start" is also available. But if I want to start the application via the store it shows me again "Content not found" and I'm again asked if I want to search for the application in the store, can someone help me with this problem?

Put the licenses in the settings of your ps4 ago maybe it works

I already worked but still not

Does your ps need an update? If not look at your download history. Can you find the news!
