You buy a chart and expect that what you’ve purchased remains intact, but it doesn’t. It degrades as they pull detailed data that you’ve already paid for. You’d expect purchased updates to provide the latest survey data, and by all rights they do — but if you don’t need the latest and greatest survey data, you’d expect the old charts you bought to show you everything you bought. Nope — they pull the rug out from underneath you and dangle a $6 chart upgrade out there with no guarantee that the corrupted view of the area of interest will be any improved after taking the bait. I’m done with this app. Open CPN on raspberry pi it is.

Kindly requested to active AIS options to be used with new navigation equipments. In new devicee we receive ship data through AIVOD sentencesb that unfortunately that is locked in the app.

Please fix the update of the chart yearly
