Hi All,
Just got back to use my smart trainer again this morning but I found that the trainer was flashing red and green, sometimes orange at that moment.
I googled and found the way to fix it via firmware update here https://blog.nihilisme.ca/amber-orange-light-on-tacx-vortex/amp/
I updated and waited about a half of an hour, since it seemed did not work, I push the cancel button..
And now my trainer showing a orange light and I cannot detect it with my phone.
