Future date and Strava
Today I found out that the reason for Strava to reject yesterdays activity, Tuin van de Mevrouw, was caused by the fact that the date in the export to Strava was 07-APR-2019. I exported the file from Connect and the import of Strava explained the issue. The repair Strava offered did not repair the file. I therefore dit it manually.
Then is showed fine and even ReLive processed it again.
