Hello @co50 – sorry you have encountered some issues with the plugin. I have been able to reproduce the bug that started in the current version with the Dashboard widget no longer showing ( https://github.com/woocommerce/woocommerce-admin/issues/2137 ) we will get that fixed for the next release.
> An hour later, no data at all in any of the new screens.
That is quite odd indeed, I have not encountered that issue myself. Are there any jobs listed as “complete” inside Scheduled Actions? ( /wp-admin/admin.php?page=wc-status&tab=action-scheduler&status=complete )
If not jobs are shown there, that would point to the jobs never being enqueued to process the historical data. I’d be happy to help work through the issue with you – did you populate the data from a backup or another means? If there is a way I can either access the data set, or re-create a similar environment I could dive in a bit further.
Thanks for taking the time to test out the plugin, again I’m sorry you encountered some issues.
