Failing to export/import messages. "0 SMS(s) and 0 MMS(s) imported"

[Savasdotexe]

After trying various combinations of settings, I'm at a loss why my SMS messages are not importing.

When exporting, I do get a message of 1900 sms and 56 mms exported in 10 seconds. The zip file size is 846KB, I can see some media in the data folder and the messages.ndjson file is 1531 KB so I am guessing it is exporting correctly, just not importing. Any suggestions or fixes?

Here's some screenshots.

Thank you for reporting this. Do your message addresses by any chance contain spaces? There's currently a bug that prevents such messages from being imported. In any event, please provide a minimal reproducible example.

Hi tmo1,

So first I tried to export then wipe and import 2 messages I had on the target device (Samsung A21s) yet still was unable to import anything. I tried the debugging option and selected 2000 and it imported successfully so I tried the same process with the large export I had it exported 1900, yet I only imported around 1700 so some messages are getting lost. If that helps.

I'll try and provide the logs in a few days, thank you.

By that you mean if some of my addresses, as in phone numbers are saved with spaces?
