kmail unable to read mail for a google account worked before works with my 2nd google account tried to delete account and start from beginning: no luck; but no authorisation window for google account access opens - wonder how this should work, added password but in account dialog but this didn't help also tried without enable calendar access, but didn't changed anything in console I get: org.kde.kgapi: Bad request QUrl("https://accounts.google.com/o/oauth2/token?prettyPrint=false") , Google replied ' "{\n \"error\": \"invalid_grant\",\n \"error_description\": \"Bad Request\"\n}" ' maybe that's the reason?
