We tried 6.12 in CCR 1036 and the next issue appears: after a few hours of normal operation, some parameters (i.e. /tool/email configs) dissapear and we need to perform a reboot in order to resume a normal operation. Along with this, simple queues stop to record data. Yesterday we were forced to downgrade to 6.6 because the missing parameter was: router password! The router allowed access with no password at all! Thanks for your time.
