the same as the title. Pls tell me. Thks.
I am not with the development team but I found this article that said: on May 4th 2016, Apple declared that as of June 1st, all apps submitted to the AppStore must support IPv6 only networking
Among others, I am using Joplin downloaded from the Appstore AND I have IPv6 disabled on my local network (nothing in, nothing out), but Jopiln on my iOS device works just fine.
One problem with your title so: "does XX supported YYY" is not a sentence which makes a lot of sense. Please try to rephrase if the problem is still relevant to you.
