Conditions should be auto-saved roughly every 3 seconds (when they have been changed) and you should see a message once it’s done. Please let me know if this is does not fix the problem!
It doesn’t seem to be saving, and I don’t see any messages. I see a confirmation, when I hit the save. But then the newly put condition is removed.
When conditions are saved automatically, it should look something like this: https://dev.institute/wp-content/uploads/auto-save-conditions.png
If the auto-save fails for some reason, a small Save button should appear where you see the spinning circle on the image.
It is not necessary to click “Update” on the sidebar if you’re just updating the conditions.
If it still doesn’t work, please let me know the name of the plugins you are using, as the problem is then likely caused by an incompatibility.
