I’m on the latest iOS on a 12 Pro Max and using the Trial version. Seeing the posts in the forums I’m not totally convinced at purchasing plus I already noticed this issue.
I’m using the Medium session setting (although I believe this occurred in Normal as well) and the countdown timer until the next break requires Opal to be open. Is this the intention? I figured the feature was to break up breaks, not also force Opal to be open. Sometimes the timer will countdown a little bit if I minimize the app, but never more than 10 seconds, and sometimes it totally resets.
I should add that Opal offers an immense opportunity to be a near-perfect productivity app but there’s work to do!
