Bug fixes and other improvements We've created an updated version of Beeper Mini that fixes an issue that caused messages not to be sent or received. You can get the update directly from beeper.com/update on your phone. We are still doing some final testing before submitting the update to the Google Play Store for distribution to all users. If you encounter any issues, you may need to uninstall and reinstall the app.
Apple could fix this by uploading the photos to iCloud and sending a link. But improving the experience of SMS chats is not profitable, so they instead actively downgrade the experience.
I always send an iCloud link for photos when I know that there’s someone who may not be using an iPhone. I’m not sure why others don’t. It’s especially useful when sending large numbers of pictures.
