Tivimate app on firestick uses more and more storage until it won't open.

We are using Tivimate Free on our Firestick and after so long, the EPG bloat will eventually take up storage space until the app won't open. If we catch it in time, we can just clear the EPG and all is well for awhile. If we don't catch it until the app won't open, we have to clear the app data and re-input the playlist and epg info (not fun on a Firestick with no keyboard).

Is there a setting that will auto-purge the EPG or will we just have to be diligent about clearing it?
