Here's what FFG posted in Reddit for 1.04 update changes, not much to be honest:
Squad Builder Update
Greetings everyone! We have a few more updates regarding the Squad Builder that we want to share with you. First, the v1.0.4 mobile update was submitted to iTunes last week and will be rolling out along with the Android update as soon as it's approved. Changes in this version include:
Added recurring charge icon to stats
Addressed layout issue related to ship costs getting cut off
Addressed issue in card database search that showed italic tags
Fix for color on linked actions icon
Layout improvements to iPhone X
Minor bug fixes and stability improvements
Additionally, other backend work has been underway, including investigation into account management and bugs related to saving squads. Some Android users have reported not being able to save their squads and our backend developers have been investigating this problem, which is likely related to the Asmodee.net account system. More details on this are coming soon.
As always, we continue to work to improve the app experience based on the feedback you provide us. If you are experiencing any issues with the Squad Builder, please email firstname.lastname@example.org with your bug report. To better facilitate these reports, please explain the bug in as much detail as possible, including:
Which version of the app the problem is occurring on (1.0.3, 1.0.4, etc)
The form of the app the problem is occurring on (Mobile, web)
The kind of device you are using (iPhone, Android, computer)
Users who have trouble logging in should also send their asmodee.net username and the email address associated with that account. We will most likely not be able to individually respond to every message, but we will send the reports along to the dev team.
Finally, we're happy to report that development on Wave II content is underway! We'll be adding support for the First Order and Resistance factions along with all the other content for the wave in mid-November. Keep checking back for more updates!
