Regarding the bag on the android version.

MediBang Paint is currently having a bag that images on all of the layers are not shown properly when users open files on the Android version.
The layer information is retained, however the image information is missing in this bag.
We have been receiving inquiries regarding this issue from several users and have been investigating the
cause at a moment.

There seems to be a problem in the process of loading images. Therefore, the file itself is not broken.
Additionally, some users have reported that they could open the same file on the PC version without experiencing the bag.
If you ever experience this error, please close the file without overwriting it.

Furthermore, it would be helpful for us to investigate the issue if you could attach the relevant file to your inquiry.
We are deeply sorry for the inconvenience, and will release the revised version as soon as possible. Thank you for your patience.
