When I click add statement on a wikidata item and then first select the property and then enter the value and then click publish normally the newly created statement is visible as expected but sometimes the new statement disappears in the moment I click publish. After reloading the page the statement is visible again.
This happens on maybe 10% of my edits I see no pattern when it happens, no error is printed in the console.
This is very annoying since I'm always not sure if it's this bug or if I accidentally pressed cancel.
