It looks like there was an update with the cloud version very recently.
When purchase invoice is made, if I put 0 in the qty but still put unit price it should count 0 in the amount. Currenly it counts like 1 and the unit price is calculated in the amount. I have hundres of invoice have been input and lots of them have 0 qty in certain items and now they are all overdue. Can you fix this asap please? See below screenshot.
Should be fixed in the latest version (21.3.88). If you are on cloud edition, go to https://cloud.manager.io then click Restart Cloud Server to force the upgrade.
