Works sometimes

I just got the Anova sous vide machine so I have only used the app 5 times. The recipes are convenient, and they all have worked well so far. There could be a few more recipes for vegetables etc. My problem with the app is 3/5 times I have used it the timer just does not start. One time it never told me it was to the set temp. The other two times it did, but the timer still did not start.
