Now every time I am starting zwift I have to plan for about 20-30mins before that it needs to update. I use the program 4-5 times per week. What is going on?
I would completely uninstall Zwift. Reboot your computer and then re-install Zwift.
Sounds like something is amiss on your machine.
It’s happened on separate machines
We typically push an update out only about once every 2 weeks, so I think you’ve hit an updater bug. If you go here and re-download the installer (it’s small) and run it it’ll upgrade to 1.0.19. That may fix the constant update problem.
