But if the clients aren't seeing changes for the same shared account, then I can't really think of any good reason for your problem. All clients are notified of all changes when Dovecot sees them. There shouldn't be any change from how v1.2 worked.

Does dovecot notify clients that drop into an idle state ?
I see a bunch of *_idle_* params, that confuse me, like

default_idle_kill = 1 mins
imap_idle_notify_interval = 2 mins
imapc_max_idle_time = 29 mins
mailbox_idle_check_interval = 30 secs

and

idle_kill = 0
or
idle_kill = 4294967295 secs

in various services
