Zotero IOS webdav not support ipv6 address
I run my own Webdav service for the syncing of Zotero and it can be accessed by a ipv4 and a ipv6 domain. It works fine with zotero on PC and Papership on IOS. In the newest version of Zotero ios, the webdav works fine with the ipv4 address, however the ipv6 address pops out "could not connect to webdav server". Does Zotero ios webdav not support ipv6?
