I do indeed have a pushcut automation server running at all times (should have mentioned this).
Thank you so much for your suggestions!
According to your input I created a shortcut which is triggered by a personal automation at midnight every day.
I got this to work initially, but iOS 15 seems to have broken a lot of my shortcuts including this one. Am I the only one?
I would post a screenshot here, so people might point out any obvious mistakes, but it’s not that complicated
Now every time this shortcut runs I get this.
