DLC's and other issues

If the devs haven't approved it, then Xbox can't do anything about it.

I understand the licensing issues in regards to car packs and similar DLC that contain products from other companies. What about the DLC, such as Rally Racing in the first Forza Horizon and Storm Island in the Xbox One edition of Forza Horizon 2? There
are other developers that do the same thing. Removing DLC that has no apparent licensing issues, without explanation, is very annoying. I am willing to accept that I won't be able to get the achievements for license related DLC. I don't like it, but will accept
it. It is all the other DLC that have achievements and the ability to newly acquire it has been disabled. That is the issue I have with DLC with achievements.

Based on other posts, this seems to be an Ubisoft server issue effecting other DLC as well.

I've been experiencing this same issue. The new DLC does not show up in Ready to Install. If you install the Season Pass, it installs the data for DLC 6, but still shows the price on the DLC 6 product page (which NONE of the other DLCs show, even when
they're uninstalled) and does not give any notification on the Xbox home pop-ups that it is ready to use like the other DLC when they are reinstalled. Due to the fact that when purchased the character works fine in the game, this seems like it's a licensing
issue, not a game server issue. Please find a fix for this, as myself and others are owed what we paid for.

So just tried to see if I could get any other dlc from the other account on to the main xbox and yes this seems to be a Rock band 4 dlc related issue.

Can download Far cry 5 with all the dlcs (bought with the other xbox and with the account I am homesharing with) So the homeshare for everything else seems to go smoothly and as it is supposed to be. The issue mainly seems to revolve around Rock band 4 dlc
for some reason.
