Button to Launch to Grid Edit Report, then redirect on save (mobile!)

Has anyone had success launching from a record to a grid edit report (via a button), and then returning from where you came when saved? But - on mobile?

On desktop it returns no matter what I do. I can not even have a redirect and it returns. I can use &rdr or &nextUrl and it returns. Basically I can do no wrong.

On mobile, on save it always goes to the app homepage. Anyone know any secrets returning from a grid edit report on mobile? So far I have tried both &rdr and &NextURL and hard coded the page, and also tried using the new:

& URLEncode(URLRoot() & "db/" & Dbid() & "?a=doredirect&z=" & Rurl())

No success with any.
