User blog:Datadragon Seraphim/Edits - Categories dissapearing

Ok, so recently I noticed that categories were dissapearing from articles when they were edited. I've experienced this problem firsthand repeatedly and several other users also experienced it. So far, what I have gathered: So, what can be surmised is that ediing with IOS/Mac OS, be it on an Apple mobile device or computer might be the cause of the problem, probably due to compatibility issues.
 * All the category dissapearences happened when a user edited on IOS/Mac OS so far
 * It happens repeatedly, is not one off
 * Multiple people experiencing it.

Anyone else with this problem, other than Datadragon Odahviing (me), Tatenicholson001 and Alador 1666?
