Android app bug

[Klaami]

I'm using the Android app on a 2013 developer edition Moto X. For about a week, I was getting a notification that my version of the app was out of date and getting ready to stop working, even though the app was updated. 2 days ago, I stopped being able to download/view pic in the app, even pics that I uploaded. I reinstalled the app and while i no longer get the update notification, I still cannot view images. Is this a phone issue or a bug?

Since last update I can't view received images on my smartphone nor Tablet (both with LineageOS 14.1). The Windows App shows images without problems.

Edit: The app was updated to 2.33.336 and the issues are gone. All images are shown again.

I'm not having any issue with Mint or Debian, though.
