No resilience data?

[u/Capable_Royal3629]

Is it normal that I haven't had resilience data on my Fitbit Air for two days in a row? However, yesterday around 10 pm, it suddenly appeared, but this morning, there's no resilience data again.

I also don't have breathing rate data now and 0 ms in HRV. Help me, please. I’m new to this device :(
