When your PastBook is created, by default it will import the captions from your social media (if created with Facebook or Instagram), to make any changes in the captions, we suggest using a tablet or computer. Some editing options are currently not available for the mobile version of the website, rest assured that we are working hard to bring this option to all our mobile users!
In case you want want to change the captions, please use a tablet or computer and then follow the instructions here.
