I created a Form and published it to a Form Library. After several edits and publishing i closed my InfoPath. After it i still can create new items at with this form, but i can't edit this form in InfoPath (Library Settings -> Advanced Settings -> Document Teplate). There is no link to "edit template". If i put a URL to the form in the Browser, i can only fill out the form, but can't customize it. Any ideas, how can i customize my Form?
P.S. SharePoint and InfoPath are 2013.
