I had to drop 2 emails . 1st email by clicking on reply and I did not get an auto generated email . Then second time a separate email with an auto generated email which was successfull. If you get an auto reply then it’s good to go . If you don’t then try again
Are you supposed to get the auto renewal ? If yes, then don’t expect as they have clearly stated that you have to apply. You have to maintain your status( Worst case scenario).
