Yea I tried all these on mobile and pc they do not perform like the button link on the embedded report tool bar button
same page just saves the record and opens the sub form
new window saves the record and opens in a new tab
pop up opens browser on pc and mobile it mimics same page
I also would like to see an option to either call the subform myself perhaps with a specific class, in a formula rich text button, or be able to modify the native button. Like you, it would be hugely helpful on mobile. I have feedback for this!
