Just won’t work

I bought this app about a month ago and it set up just fine. However, now it just won’t work. The thermometer shows it is connected to my wireless - but it no longer connects to the app! Ive re-set it, and called WS for support. They told me to swap it out for a new one at a local WS store. OK -I did this: Ive also re-installed the app - and nothing. The thermometer won’t show up in my settings unless I do a hard re-set; after I do the re-set, the thermometer disappears from my wi fi settings. The app is useless to me and the thermometer is just another probe thermometer without it - and a very expensive one which I don’t need. This is going back to the WS asap! Not worth the time I’ve spent trying to get it to work
