At first intro screen, if mailbox app pushed into the background then foreground - it skips the rest of the intro screens

Device used: Samsung 6810 API 16, Android 4.1.2

Steps to reproduce

• fresh install mailbox
• when the first intro screen shows, push the mailbox app into the background, and open any other app for a short while
• then go back to the mailbox app.

Expected results:

• mailbox should be showing the first intro screen again as the user did not make any selection there -no tap on either skip intro, or on the continue button)

Actual results:

• mailbox displays the progress wheel instead of the expected intro screens

This happens with both do-not-keep-activities selected and not selected. Will now try another device

OK, it can also be reproduced on Samsung A01 Core, Android 10, do-not-keep(activities = ON as well as OFF) On this device, if I leave the mailbox app in the background and open another app for a short while, then go back to the mailbox - instead of the first intro screen, I see the do-not-kill-me fragment. I would expect, like above, to see the first intro screen again because I didn't make any selection on that screen before I pushed the app into the background.
