Please accept this in the ethos of no stupid questions.
The only programming I do is to defy tracking by deleting hash lines after ? In the url.
Some popular sites I am embarrassed to admit to even viewing have found a way around this by offering me share links without the ?.
It’s Instagram I am ashamed to mention.
What do I do to get rid of the tracking now?
Chances are they are doing something similar to URL shortening where a reference to the destination and the tracking info is either hashed into the URL directly or stored elsewhere behind whatever ID is in the URL.
Unshortening tools can fetch the actual URL (with any tracking params) in a private context.
I have no idea if anything exists on iOS, but on Android there are tools like URL Check which replace your default browser and let you un-short or otherwise manipulate URLs before opening in a browser or sharing.
