Hey Bogdan,
Thanks for reaching out and sorry to hear about your issue. I’l try to help you out figuring what’s wrong in there.
Can you elaborate a bit more on this? Was this working as expected and then it stopped working? Can you send me a screenshot of the orders page? Also can you check the server time and date are correct (you’ll see a quick sample of the current date in WP-Admin > Settings > General > Timezone)?
If all looks good, Can you please follow the steps described in our Testing for conflicts guide? This way we can see if this is a problem in our plugin or a conflict with the theme or other installed plugins.
Please let me know about your findings,
Best,
Nico
