We Recently Upgraded Ignition from 8.1.12 to 8.1.27. after the Update, the Find option in the designer is not working properly. Even a straight forward Tag search, Named Query search is not returning any result event after applying correct filters.
Have anyone else faced this same issue? Not sure if its because of faulty Installation during Upgrade or something.
Also there were few Internal tags deleted after upgrade. It seems strange.
We should really get a project backup off to IA support so they can investigate the cause. If you can send off your original 8.1.19 project which didn't have the issue until upgraded to 8.1.27, that would most likely help the most.
