Hello, our Chrome browsers have been recently updated to version 100 from 99 and every time we try to save changes to a web map in ArcOnline (new or existing web map), Chrome completely crashes and changes are not saved. When my manager still had version 99 and I had 100, he was still able to save web maps. Since his browser was updated, he is also not able to save web maps now.
Are you using Map Viewer Classic or New Map Viewer?
I am on Version 100.0.4896.127 (Official Build) (64-bit) and not seeing any crashes in either viewers. If you have an existing web map that's reproducing please share it if possible.
My manager & I realized if the browser cache/data & cookies are deleted, ArcOnline refreshed & log back in, it works. So I guess, when it happens again, clearing browser will be the solution.
