Question One App won't show notifications

[Sarah83]

Hi all,
Hope someone can help me here. Since upgrading to S25, one particular (important to me) app won't show notifications anymore.
I have attached screenshots of my settings. Please can anyone advise? The app company will not help me as they say the issue must be with my phone and not on their end.
Thanks in advance,
S
