Since the last update Deezer has not worked in the background whenever I use a timer application.
I've been working as a Personal Trainer, and I've been using Deezer with a timer app for over two years, never having a problem with Deezer stopping playing when a song ends.
I do not use any memory or cache cleanup applications and do not leave the "power saving" feature enabled on my IPhone 7.
As I mentioned before, I've been using Deezer with a timer application for over two years, without ever having the aforementioned problem, I think it's a bug.
I sincerely hope that the problem is solved, otherwise I will be forced to switch to Spotify, which I do not have this problem. Thanks!
