### 2/5 — Not Working!

*2026-01-28*

Recently purchased and Installed app to my iPhone, entered serial numbers for monitor.  I bought 3 monitors for 2 cars and a boat.  All entered easily and worked well initially.  Now the app will not stay open and if it does open at all it is “frozen” and does not function.  No way to refresh or update via App Store as it closes immediately.  I will have to delete the app and re register all the monitor serial numbers I am guessing.   “Big Pain in the battery!”
