Solved.
got it working with conditional groups (glad they are available now).
Logic is:
Show field 3 when, (field 2 is empty and field 1 does not contain “word”) or (field 2 is not empty and field 1 does not contain “word”) or (field 2 is empty and field 1 contains “word”)
Basically need to make list in the condition groups for all possible options.

Hi there!
To give you even more options to work with conditional fields, at miniExtensions, we've created a third-party form that integrates seamlessly with Airtable. With our form, you can create individual or grouped conditions to show or hide fields based on the values of other fields. Plus, with our versatile Save & Continue mode, you can calculate formula fields and use them to control field visibility as well!

You can calculate the formulas manually before submitting the form or periodically every few seconds:

Feel free to try out these features with a free account on miniExtensions 👍
