Did you know you can add more than one picture to your activities?
For that, in the creation form, access the “Pictures” (Android) or “Carousel of photos and drawing” (iOS), click on the camera icon and on “Select from gallery” (Android) or “Select photo from Image Gallery” (iOS).
You can select more than one picture at the same time from your image gallery. On Android you can choose up to 5 and on iOS up to 10.
Lastly save the activity and... ready! You have already associated your images to your sales activity, being able to review that when needed.
