First of all,this is not the right way to answer a customer.

Find the attached video containing the following procedures :

1. List of tags has been displayed.
2. Tag is being bound to a component via expression
3. Then a new tag is created within the same folder.

Now when i try to bind this new tag to the component , i could not find the tag reference , it’s bug.

That’s quite the collection of sideways videos. Is the issue that a newly created tag is not available in the selection list when editing/creating an expression binding?

Two of your videos are not viewable (at least by me).

It would also help to know which version of Ignition you are using. I am not able to reproduce this under 8.0.6RC1, using every binding method I could think of. 😕
