[BUG] Temperature unit fallback to F randomly

In my watch face I use #WM# parameter to check, if user uses C or F weather units. Also I use weather forecast like #WFAH#, which automatically uses F or C units according to facer app setting.
Unfortunately after last few Facer update, watch face switch to F several times a day, even when C is selected as preferred. User needs to go to mobile phone Facer app, change weather unit to F, back to C, wait a while and watch face is updated. This is quite annoying, doing this multiple times a day.
Anyone experiencing similar?
