Re: Android 11: App polling interval is not 15 minutes minimum?

So using BlueMail or K-9 Mail on *Android* as an *extra* mail client,
can solve your problem of *manually* polling your *Spam* folder when
you expect, but don't see/get the email with the 2SV code in your
Inbox.

After delving into their online articles, I found:

https://bluemail.me/help/sync-options/

which mentions "Manual" for refresh (fetch), but manual refresh, or
fetch (other than sync settings), and "poll" has no hits.  I went back
to Google to search on "bluemail manual refresh", and found:

view-source:https://bluemail.me/help/refresh-mail-list/

but that's a blank page.  Looks like a Javascripted dynamic page, and
they screwed up on the .js resources.  I'm not blocking Javascript on my
visit to their page.

Refreshing the Mail List
To refresh the Mail List, pull the screen down (swipe your finger from
the top of the screen downwards)

So, it's there although called refresh instead of poll or fetch.  It's
there, but not obvious, plus I'm likely to pull down the notification
shade.  App devs seem to think you just miraculously divine how to
operate them.

I didn't spend time determining how to do a manual fetch in K9.  I
looked a bit more at the Gmail app bundled on my phone (and one of those
that won't let you uninstall the app unless you use ADB to remove the
package).  It will let you do a manual sync, but again how to do it is
very obtuse.  In Gmail app's menu -> Settings, tape the 3-dot menu icon
to select Manage accounts.  Pick the account, and the next screen shows
a Sync icon.  Geez, what a pain.  However, divining to drag down from
the top of Bluemail's screen is just as unintuitive.  This route to
manage accounts is the same one found by going to Android settings ->
Accounts, picking an account, and tapping the Sync icon.  Apparently the
manual fetch is an Android option instead of within the app.

Instead of installing another e-mail app, or switching to the Gmail app,
or wading through menues to get at the Sync button to circumvent long
fetch intervals on the Junk folder to see false positives, like 2FA
codes, I might as well as install the bank's app which I've done.  While
there is no external app lock available in Android to put on the bank
app, it does require me to use a fingerprint and enter a 4-digit PIN.
Eh, guess that's okay.

I asked the bank about TOTP with their Android app.  They don't know, so
how their app authenticates is unknown.
