Not just the app, we have to sync them with eWeLink WEB and CAST. And our design team also has to redesign or fine-tune them from time to time.
Uploading images to the cloud is also troublesome; just think: every time you open up the app/WEB, you have to wait for all kinds of pictures to load up, depending on your network condition. Stock device images have strict guidelines in design and size, format, and ratio optimized for all eWeLink platforms.
