Hi,
During my last 4 runs, my altitude readings have been erratic starting mid run.
Roughly after 30-40 minutes of running, suddenly the altitude readings are spiking and going crazy: I'm running on a road, so basically it's flat!
As a result, the global elevation of my runs are totally wrong: yesterday the watch indicated 417m D+ for a run where I usually have 50m D+
I checked with the previous firmware and never seen such readings.
I tried to clean the barometer holes after the run, but any hint to fix that would be much appreciated.
