I'm not sure it's a bug, but looks a bit weird:
I have 2 IG accs. Today I've posted to both of them, and got a funny result: in my Macbook Diarium for today I have a pic from one IG acc, in my Android phone Diarium for today I have pics from the other IG acc.
To make sure it is so I've logged into both IG accs on my both devices.
I'd prefer to have a choice what acc to connect with Diarium since one acc is for my work and I don't want to see these posts in my private Diary.
When I purchased a full version of the app I connected it to only one IG acc (on Mac I picked my private IG acc).
Diarium version: 3.0.68

Device model: MacBook Retina 12" 2017
Diarium version: 3.0.68
