Strava has a feature that allows you to upload photos to either document your ride, help you remember where you were and what you were doing, what conditions were like, etc. But sometimes when you try and add photos you get this – a blank screen – but you can still select missing images…?
Missing Strava images
Are you using iCloud to store your photos?
If you are using iCloud to store photos, what’s (probably) happened is iOS has helpfully pushed all your images up to the cloud – so when Strava looks for them it doesn’t see any local thumbnails. If you go to the Photos app and tap on the images you want, iOS will download them again, and Strava will now be able to see the thumbnails.
TIP: if you use iOS’s ‘Low Power Mode’, then your recent images will stay on your phone for longer – or at least ’till you connect to a known Wi-Fi network.
