Hi ​@MY20, try the following - in the Strava app, open the tab You, then tap the  / settings icon in the top right corner, then Manage apps and devices, tap the device/service you want to sync, and you should see a list of activities from last 30 days. Those already imported should have a checkmark, those pending should have an “Import” sign next to them. Tap that - and shortly you should see a notification that your activity is ready to view. 

​@Jana_S Hi, I don’t see anything under the “Manage apps and devices” section

Hi ​@Jana_S I dont see my device/service that I have synced with in the “Manage apps and devices” category

​@MY20 well how did you set up syncing from the Mi Fitness? It should be displayed in the settings if it's added…

I’m using a different device myself so I don't know what exactly it looks like with Mi Fitness, so hopefully someone else does and will have more detailed instructions in case you can't find it.  

Ok I now see also the screenshot (it was probably waiting to be approved by a moderator), what do you see when you tap the “Google Fit”?
