omgomg!
Rider, that totally worked!
After spending hours and *hours* submitting and reopening tickets about my dead Merchant Outbox, downloading various viewers, logging in, logging out, submitting a debug report, writing a jira, and searching any and all avenues I could think of (since LL was less than no help at all and I got the exact same canned responses you guys did),
I finally ended up here.
And I changed my website language to French. And then I changed it back again. And now my Merchant Outbox is working like a charm.
Words fail...really.
Except, thankyouthankyou Rider for coming back and proclaiming what worked, as patently absurd as it was.
Hugz and bestaluck,
Dagmar
