I’m trying to do TurboTax through my Lyft dashboard, it’s telling me I have to update my browser, I’m using my iPhone and it is updated how do I proceed

The discount thru LYFT doesn't work on the mobile app... you need to use a full computer and login online. 

I have same problem. I rate the Lyft driver discount, but per instructions read that I must access TurboTax through the Lyft portal (not available for install on my computer/MacBook Pro).  And as far as I can see, my iPhone is totally up to date and each of its browsers, so why does the prompt page to update keep blocking my login?

I’ve not tried access via my tablet yet.
