MuseScore Mobile playback prematurely executes Tempo changes

I have noticed that on one of my new scores, and only on the mobile version, the playback tempo changes are happening at the incorrect times. To reproduce:

1) Open the MuseScore app.
2) Go to the score Culver's Symphony No. 1
3) Go to about 13:10 (other times where there are tempo changes also work.)

Notice that the score begins to slow down prior to me causing a tempo change. This is not reproducible on the website, nor is it reproducible on the application.
