A quick note. Some users have had difficulties upgrading our recent introduced apps, SEAiq Open and SEAiq Free. We have a fix in process to be released by Apple, but in the mean time here is some help for users running into this issue.
While the SEAiq apps do not need to be connected to the internet to run as chart plotters, they do need to be connected to purchase the upgrade from the Apple iTunes store. If they are not connected when the app first launches, IOS can give up trying to get information it needs to purchase the upgrade. The symptom is the button on the Store tab says "Wait" without ever changing to "Buy" (which normally should only take a few seconds). The workaround is to make sure you are connected to the internet and then restart the app (or restart the iPad/iDevice).
Again, this is only an issue when purchasing the upgrade. Afterwards, you do not need to be connected to the internet to use SEAiq.
