There have been several bugs with the Snap app of NordPass with these two issues:
1.) Every time I try to log in, the indicator is either invisible or partially shown.
2.) Every time I right-click on the icon for its menu, it’s all in blocks.
Is there anything I can do to fix these issues?
Well, as it Snap related, I doubt it’s linked to Manjaro.
I don’t know if it would work on a VM, but if you have another Linux system installed, you could try the application on it to check if the issue is still there.
Anyway, on their Snap page, there is a link to their website, as well as a contact mail:
You should talk to the developers of said application.
