I am not sure are these related at all but after updating HassOS 4.14 lovelace cards lost the history data when casted on Google devices. For instance the card below shows only the state 2.5 C but not the graph when casted on Google Nest Hub or chromecast unit. With HassOS 4.13 I did not see this problem.
EDIT: Rebooting the Host System fixed the problem for me
I never found a solution - I have seen this as a problem for other people also. I opened an issue of this - please comment in github to speed up solution for this matter.
