auto-post Instagram Reels where you are added as collaborator (not original creator) to YouTube and TikTok
You can auto-post Instagram Reels where you are added as collaborator (not original creator) to YouTube and TikTok using OneUp.
In OneUp, you can set up an auto-post workflow so that any time you post a Reel to your Instagram account OR get added as a collaborator to a IG Reel, it will automatically post it to YouTube, TikTok, and any other social networks you select.
Here is a video showing how it works:
In OneUp, you would create an auto cross-posting workflow like this, where you would choose your Instagram account as the Source account (POST FROM) and your YouTube and TikTok account as the Destination account (POST TO):

And yes, this DOES work even with Instagram collaborator posts where you are not the original author.
Once you have the workflow set up, whenever you accept a collab request on Instagram, OneUp will automatically post it to your YouTube and TikTok (and any other social networks you select) within 2 hours.
