It worked pretty well last night on several Forlorn Hope wines and a Metras. Consistently got the producer and it was easy to correct to the specific wine. I think some of your delays are because the Delectable team has likely been drunk on Vurgundy the past several days.
I haven’t had that exact issue, but I have noticed since the last update (March 8, v5.6) that the recognition engine seems to be messed up. For my last 4 bottles it accurately determined the correct winery, but missed on the variety (e.g. said a Chardonnay was a Syrah, picked the wrong vineyard for a SVD, etc.). Not sure if this is related, but there might be an issue with the latest release. I had to use the lookup/search feature to correct all four…usually it is quite accurate (at least for me).
I have a question for you. I cannot update my Delectable on my iPad. When I go to updates and click on Delectable all it does is open the app. I tried to delete the app and reinstall but it does not show in settings.
I stopped using this app when they couldn’t identify a couple wines I submitted accurately. (They guessed.) They claim to be the experts, so if I can extrapolate from what I experienced, there are more potential mistakes yet to be found.
