Where are the DLC's (gta four)?

Back then I bought four digital dlcs on the xbox 360 gta with both dlcs. Now I have gta four back on the series x and actually also the DLC's, these are actually downloaded. However, there's no visible way to play one of the dlcs. How can i play them? I downloaded gta four and the DLC's.

Go to "My games and apps" on your console, and select the game GTA IV with the start button instead of the A button, through the start window you select "Manage games and addons", and go and press A again directly. (If you have connected a hard drive, a window will appear where it says: "Manage installation on xxxxx" and "Move or copy" - select the first one) - you will now see the game and all the DLCs that you should have bought. If the DLCs are unchecked, it means you still need to download them. Put a tick next to all DLCs and press on "Save changes" on A.

Small note:

If the installation management only shows the game and NO DLC, it means that you have NOT purchased these DLCs with your currently selected Xbox account.

Unfortunately this did not work

What exactly did not work?

It was not displayed in the game even though I reinstalled the DLC on the x. I installed them, but they won't play, but I definitely installed them. It's kind of weird…

Then I recommend that you write down the https://support.xbox.com/...contact-us.
