Skydemon (on both the Android and PC platforms) consistently doesn't show the METAR for ESCM, while the TAF is shown. Checking other Swedish airfields, right now Skydemon also doesn't show the METAR for ESNV. (Although both METARs show on both the Swedish and Danish weather briefing websites.)
I reported this half a year or so ago, and Tim wrote that he hoped than a bug fix would have resolved the problem, but apparently not.
Both ESCM and ESNV have autometars when the ATS unit is closed, so there should always be a METAR available.
