Issue with Monologue on 2 different computers

Hey - I have downloaded Monologue desktop app on 2 different computers and it started working on the first (a Macbook Pro). Then I installed it on the second and it worked well on the 2nd (a Macbook Air). Now it won’t work on the first computer (still works on the Macbook Air).

Not sure if this is intended, but just flagging it as mildly annoying (I’m having to use Superwhisper on the other again sadly).
