Thank you for all of your patience while waiting for a reply. I understand how upsetting this may be, and I'm happy to assist you with this. Which internet browser are you using? When you're trying to access your footage, are you getting any errors? Or just the buffering? Have you tried to clear your cache and cookies as well? Please let me know!
I recommend that you restart your device. This process should keep all your settings, and reconnect it to the same Wi-Fi network. This is helpful if it ever freezes, has connection problems, or isn't working normally. Once it has been restarted, clear your cache and cookies and try again.
