I’m experiencing the same exact thing. I am up-to-date on all updates. I see the following misspelling in the log file too, which is unusual.
2020-09-20T22:18:16+00:00 NOTICE order_sumbit :: #1546 has a financial status of pending and was skipped.
2020-09-20T22:18:16+00:00 NOTICE order_sumbit :: #1547 has a financial status of pending and was skipped.
Looks like a dev was typing too fast. Shouldn’t “order_sumbit” be “order_submit” ?
Also, this doesn’t happen all the time. I have orders that go through fine, then some that get duplicated or even triplicated.
