TVE Can't sign into Verizon Fios

Hello,
I'm having trouble trying to add Verizon Fios as a TVE source. I get the error " no login form found". I'm able to log into the Verizon TV app no problem. Any thoughts on this?

Can you login and watch on nbc.com/live

Same issue. I'm streaming NBC live in another tab but still get the NBCENTERTAINMENT subscription required. Have tried multiple times. Fios is getting annoying. This is making the monthly login actually frustrating.
