How do you successfully import & merge & overwrite multiple keepass.kdbx files between Windows & Android?

How do you successfully import & merge & overwrite keepass.kdbx files
between Windows & Android (when you edit on both platforms)?

If I make a change on Android in Keepass2Android & save,
and then I make a change in Windows in Keepass, & save,
when I import the files, it's not currently merging.

In Windows, for example, I run this sequence:
Keepass Password Safe version 2.39.1

For some reason, the desktop "File Import" doesn't seem to merge data:
KeepssPasswordSafe: File Import KeePass (KDBX) 2.x android.kdbx OK
(o)Overwrite if newer (KeePass will compare the last-modified times of the
groups/entries and replace the existing ones only if the ones to import are
newer) OK

Neither does the desktop Keepass Synchronize option:
KeepssPasswordSafe: File Synchronize Synchronize with File
android.kdbx

Which option do YOU use to synchronize your keepass kdbx files when you
make additions and changes and deletions on _both_ the Android device and
on Windows 10?

But it should be enough to just port the offline file between the Android and Windows and do syncing on Windows.

Yup.

The methodolgy turns out to be simple between Android & Windows.
1. Keep the "master file" on the desktop
2. Export/Import that master file to Android
3. When changes are made on Android, "syncrhonize" to the desktop

The only caveat is that for synchronize to work, the desktop keepass.kdbx
file has to have an _older_ datestamp than the Android keepass.kdbx file
(which, is strange since the data entry is what matters - not the file
date).

OK. I finally figured it out - I think.
o I wish someone had told me that 3 of the 4 Android Keepass apps are
fundamentally worthless for use on a home network simultaneously with a
keepass kdbx file on the home network.

Given the test results below, I think I solved the dilemma of _why_ Poutnik
had a synchronize in his Android version of Keepass while I couldn't find a
synchronize on my Android version of Keepass (where synchronize was on the
Windows version only).

So far, this is what I've been able to ascertain by empirical tests today.
BEST to Worst:
1. Keepass2Android Password Safe
2. Keepass2Android Offline
3. KeePass DX
4. KeePassDroid
Where, if you modify the passwd file on both Android & the desktop, the
only viable answer, really, is "Keepass2Android Password Safe", and where
the latter two are nearly worthless on a network, as they're really
stand-alone apps.

On Android, these are the main issues with free KeePass clones:

*Keepass2Android Password Safe*
o Change Database filespec option exists (on the padlock screen)
o An import database option exists (imports to internal folder)
o An export option exists
o A synchronize option exists

*Keepass2Android Offline*
o Change Database filespec option exists (on the opening screen)
o An import database option exists (imports to internal folder)
o An export option exists
o No synchronize option could be found

*KeePass DX*
o Change Database filespec option exists (on the opening screen)
o No import option could be found
o No export option could be found
o No synchronize option could be found

*KeePassDroid*
o Default = /storage/emulated/0/keepass/keepass.kdbx
o Amazingly, it doesn't seem to be able to change that filespec!
o No import option could be found
o No export option could be found
o No synchronize option could be found

While I might have made a mistake in that emperical summary above, if my
tests above can be repeated, then it seems very clear the only tool that
has all four options of synchromize, import, export, and change database
filespec ... is ...
o *Keepass2Android Password Safe*
https://play.google.com/store/apps/details?id=keepass2android.keepass2android

This *Keepass2Android Password Safe* also had the option of selecting the
kdbx file from a variety of inputs, from dropbox, to Google Drive,
OneDrive, SFTP, FTP, HTTP WebDav, OwnCloud, NextCloud, PCloud, or
third-party apps.

As an aside, all four had the option of using the fingerprint reader (which
I don't bother with as I don't even have a PIN on my phone).
