@portpass1974 Data should not be lost moving back a version to 2.8.6
@Jantan, keep in mind you are using a very good product, and it has not cost you anything as your using our totally free version. Your expectation seems very high, for something that was given to you for free.
While we certainly hold high expectations for our builder, even the free version, you may also note that developers are dealing with constant changes in Wordpress Updates and Major Rollouts. Sometimes it takes a little time to see what WordPress itself has changed before we can address or fix a new issue completely.
