Updated to version 18.104.22.1689 on my home computer. To get all bookmarks from version 5.3.8, I went to the bookmark manager 22.214.171.1249, deleted all bookmarks, then in the settings I selected "Import Maxthon 5 account data from the server". Everything synced fine on my home computer. But on other computers, when you first run 126.96.36.1999, all bookmarks disappear and do not appear anymore! The sync works fine though. Updated to version 188.8.131.520 - the problem was not solved. When removing and "clean" installation of 184.108.40.2060, the situation has not changed. On version 220.127.116.110 for android, all bookmarks also disappeared and no longer appear !!
