Manually allow app from firewall every update

Hello everyone,

my WhatsApp desktop client doesn’t ask for internet permissions, like ever.
I know that after an update, I have to reallow it, but every other application asks in the notification area for it.

It is only this specific app that I noticed.
And this brief moment to figure out… hmm why doesn’t it work anymore and then having to open glass wire and search it in the list every two days is a bit clunky.

So is this a bug, or something app specific?

Thanks for your help.
