Several Pins have URLs in the notes. I’m testing this, but at the moment think the affected Pins are all in one Group I created by importing a GPX converted from a KML.
When I tap the URL in he Notes, I get a URL in Safari that has the text %E2%80%8E attached to the end of the URL. I sure there is no such text in the Note itself: At least, no visible text, and, when I edit and place the cursor, I cannot make it place “off” the last letter of the URL.
%E2%80%8E is the escape sequence for an invisible Unicode Control character which is used to indicate left-to-right writing direction of the script. There is a known issue with WordPress based web sites where it appends this to some links. I am guessing you copy and pasted such a link from a WordPress site into Pocket Earth.
We will investigate further to see if we can automatically “sanitize” the notes field to remove such things.
