Importing Kotatsu backups not working properly #53
Description
Brief summary
when I try importing a Kotatsu backup zip, most of the data from it does not load into Futon, whether it be the library history, updates and also favorites. weirdly enough when I try to backup Futon and check its files, I can see that the files are nearly same in size compared to the Kotatsu ones. (I don't have a JSON viewer or editor on my phone, but taking a quick look using MiXplorer's Code Editor I can see that the contents of " history" in both backups are pretty similar).
I wonder if there's a specific formatting difference that I'm not noticing.
Steps to reproduce
- On
Kotatsu:
- Go to Settings.
- Tab on "Backup and restore".
- Tab on "Create data backup".
- On
Futon:
- Go to Settings.
- Tab on "Backup and restore".
- Tab on "Restore from backup".
Afterwards, you can create a backup for Futon and then compare both the Kotatsu and Futon backups.

I attached both of their respective backup zips here if you would like to try it out. (Warning: mostly NSFW stuff)

interestingly, they work properly on both Kotatsu Redo and Kotatsu Next. I wonder why.
(it technically also works on Usagi but that app is still a work in progress).

if they work on those then it should work here

Does this still exist in the new version?
NonSnameX commentedon Jun 19, 2026

LandWarderer2772 commentedon Jul 14, 2026
