Images Only Loading When App Is Opened In Time

[rafesoft]

Hello,
I'm looking for help to troubleshoot an inconsistant issue I've been experiencing with AirMessage On Android. I hope I can explain properly, feel free to ask for clarifications.
From what I can tell, and correct me if wrong, it seems by design that the application only loads in images when you open the enclosing chat. This is fine of course, however, I'm seeing that if I don't open the chat within a certain amount of time the image / video will fail to load when I get around to it.
For example: I receive a video while at work and can't open the app to see it until a few hours later. I'll open the chat and receive a message that it failed to retrieve the attachment.
This doesn't happen every time, but when I check immediately after receiving the notification it consistently loads just fine.

Very odd, is there anything I can try to fix this issue? Maybe there is a way to have these load in the background so they are already retrieved when I go to the app? If so that may be a viable workaround for me.
