I am having the same problem, I contacted TT & they said that I should input it myself, then they hung up on me. I purchased the premier version so I would not have to do this. Poor customer service.
I'm having the same problem in Feb 2026. Support agent said try different browser, still didn't work. Another agent said it is a known problem which they are working on. No estimate as to when it might be fixed. Suggested I enter manually. Seriously? Why would I buy TT just to enter this data manually. I've used TT for probably more than 20 years. Worst experience ever.
