Since updating via OTA notifications stopped working for built in Mail app… I have tried several of the suggestions found here in the forum for people with similar issues but without success. In addition, on several occasions I was unable to send email with my e.email address. Also, occasionally the Musicolet app cannot play music over bluetooth while the screen is off. I have since reverted to the August 7 build and all of the problems vanished completely. I hope this is the appropriate area to address these quirks but if not please let me know.
