This bug is realy annoying...in the past i mixed up the telegram acounts with two different bq4.5 ..so the bug rises again from time to time and i am running out of mail addresses for the ubuntu_one accounts there might be a sort of workarround using a chatbot, raspberry and vpn, to get the new messages the chstbot grapps...

yea sometimes the update seems to stock.?i am currently also on rc7...and i recognized by an other bq4.5 which is on the stable chanel, that st2 comes about one month delayed...
