Thank you for contacting Avenza Support! I wasn’t able to reproduce this error with our devices in-house when I import multiple maps from Dropbox. Are you able to send the dropbox link to email@example.com, with Attention Bob in the subject line, and I can see if there is an issue with the data? As well, do you have an unlimited imports subscription on both devices? If there isn’t a subscription on your iPad but there is on your iPhone, could cause an issue with the imports. As well, when you say the additional files are Paused, are they paused from the start? It should have text saying “Waiting to Download” while the other maps download.
