Thank you for your reply!
Is this by design or it's a bug? Why the template works for an older version (2.x) of desktop tool?
If it's by design, maybe your company shall update the online doc for WebUI template pages, and the online documents for adcenter desktop tool to clear the confusion -- clearly define the limitation for each template. Both tools (Web and Desktop) has import feature, but they are not using the same file format or has bugs, that's it's pluzzling to the users.
Please help provide the feedback to the product teams.
Best regards
