Cannot Edit Form: edit option just does not appear

Hello, Cannot edit a previously existing form. The edit option just does not appear. I have created a new form, and the edit option appears for that.

Greetings,

I've checked your account and those forms are shared with you by another user. Thus, reason why you can't edit the forms is that owner of those forms set permissions for you to only view submissions.

Hence, if you want to be able to edit the forms, please ask the owner of the forms to change permission for you.

Please let us know if you have any further questions.

Thank you in advance!
