I raised a support ticket 24 hours ago, I have latested paid version of emclient. no one has replied and now i find this problem with javascript is years old. sadly none of the methods described help me, i cannot sync my google contacts, but the gmail account and folders all come in via imap. i have tried all the changes with browsers, 2 step verification turned off etc. nothing works and emclient don’t seem to give a stuff. i have 2100 contacts i need back in my email program,
my support ticket will soon 48 hours without even being assigned or acknowledged.
I have the same problem … started a new account to see if I could solve the problem and received a reply that the Mozilla firefox browser does not have javascript enabled (firefox changed the way they handle it from v55 onwards)
