[GNC] Import transactions

[ddemott at juno.com]

I'm new to GnuCash and trying to learn and use some of its features. I downloaded version 3.1 and experiencing some very unexpected behavior. In particular, I'm trying (unsuccessfully) to export transactions from GnuCash for Android and import them into GnuCash. Here's what I experience: GnuCash for AndroidSolicits filename before selecting the export type (qif, xml). Regardless what I specify, ".zip" appends to the filename.
Selecting 'qif' crashes the app.
Selecting 'xml' works but I discovered that the resultant file is not actually "zipped".
Exporting to 'xml' does not allow the same date selection and delete after exporting options as offered for 'qif' exports.
GnuCashRenaming the 'xml' file exported from Android to '.gnucash' will open with my transactions. Unfortunately, I can neither import transactions from a 'gnucash' file nor can I export transactions to a 'qif' file.
I can export to 'csv' but I must manually expand every account branch before I can successfully include all sub-accounts for export.
GnuCash will not import transactions from the same 'csv' file it exported.
I'm trying to create proper expectations. Can someone please tell me whether these characteristics are imagined or real, bugs or features? Dale DeMott
