How do I get Arlo to play on Blackberry 10. OS? Always did, an now it does not.

[BiomedTG]

My system seems to work fine, but as of yesterday, my phone won't play the arlo video following an alert. The video seems to load ok, but my phone screen stays stuck on the Arlo bird just transmitting with hisgreen wings. When I log in to the system from my phone, I get the "Arlo isn't responding" pop up. I have tried re-booting computer and phone - without gaining success for solving the phone issue. Any ideas please?

Did the phone use flash at one time? ... sounds like a flash issue

Test on a computer/browser to see if the system is working at https://arlo.netgear.com/
