Email Action not populating Subject line in mobile Gmail

[BMAP]

EDIT: I am using (having troubles with) myapp via the AppSheet Android App. If I access myapp via a mobile browser the email Subject line properly populates.

---

I modified the System Generated “Email Action” to include a custom Subject line.

It works fine from the PC with desktop Gmail client, but not my Android device with mobile Gmail.

Is this a bug, an error on my part or is custom subject not supported with mobile Gmail?

TIA

Are you able to take a printscreen from that situation so I could be 100% sure we are on the same page

Thank you for looking at this.

The screenshot with the “File No”= “OSE0001” is using Gmail on my PC, note the “powered by AppSheet.com”

My Android Gmail has neither the FileNo. nor “Appsheet.com” the branding tag at the bottom.

Sincerely
