Directo II not working with AppleTv/Zwift ERG mode

After I bought Directo II new and use with AppleTV/Zwift in ERG mode it worked (was a bit slow like 10 seconds) but worked fine. But, over time ERG got slow and slower and now doesn't work at all.

What can I do to 'reset' the Directo and/or apply firmware patch to fix the ERG problem on the Directo?

Thanks in advance.
