Hi @Nandan Hegde ,
As per internal discussion with the products team it can be confirmed as an UI bug, in which case we missed File share text box when SasUri is referenced with an AKV.
Products team is actively working on the fix and planning to roll it out to production mostly by the end of next week. I will confirm you back over here once it is fixed in production.
Appreciate your patience and thanks for reporting this issue.
Thanks
Saurabh
