Hi Community,
We believe we have addressed this latest posting issue for the most part and, while you still may see listings go into "Posting" status on your Scheduled Listings page temporarily before your items are actually posted to eBay, we are monitoring things closely will ensure there are as few failures as possible.
If any listings that you attempt to post after this time end up failing to post due to error messages that say "Not Posted in Time", please let us know by filing a support case. Thanks again for bearing with us!
-Mike
