We just tried to install the update to version 5.0.0 from free version 4.3.3 on our staging site and found that the newer version breaks existing grouped product variations from being viewed. This is a show stopper for existing sites. If variations and or variable existed on the sites prior to the upgrade, why would they be disabled as part of the update? Is this a bug or by design to force users into the premium version? Please provide guidance and better details during updates that notify users of possible loss of existing functions when an update is installed. If the premium version is REQUIRED to maintain the old functionality, then will the purchase of the SINGLE site license allow us to install that same license on our staging site?
