Informant 4.94 and iOS 10/11 Updates, lost my purchase info and now I'm being asked to buy again...
If your previous Informant application was Informant 4.9 or later you can restore your previous purchases doing the following-
If you have a subscribed version of Informant meaning that you pay monthly for the application and sync service you will need to make sure that your Informant Sync account is signed in and has synced at least once to keep the application unlocked for you.
If you are not a subscribed customer but purchased Informant once please go into the Informant settings, and tap restore purchases.
If the purchases are not restored please open a case to our support team.
