Sorry for my late response. Thank you for all of your patience while waiting for a reply. I just wanted to make sure that your issue is addressed. I am terribly sorry to hear that you have had such a hard time with this! I would love to look into this issue further and help find a solution for you. First off, I have some questions I’d like to ask you.
Do you still need help with this issue?
What troubleshooting steps have you done thus far?
Have you tried to restart your device if you haven’t already?
If the restart didn’t work, have you tried to do a Factory Reset? This would be a last resort option, but would clear out issues and the device would essentially be ‘brand new’
Please let me know if you need further assistance.
