Thanks for the hint. That could be the reason I get this on nightly since .. about four weeks (or six weeks? something like that). Seems to concede with the time the new privacy protections went on by default.
I've only just noticed it, but mostly because I've forced myself not to install the Twitter app nor login to my account on the particular device I've been experiencing all these "Something Went Wrong" errors. I assumed it was a "feature" to encourage people to login to the app caused from a bug somewhere in the ad stack, and this seems to corroborate that hunch.
