purchasing an app that is free for a limited time but to pay on an app update
good day!
i once purchased an app that was free for a limited time. the promo period ended and it went back to being a paid app. on an update notification of the app it appeared that i have now to pay the app to get the update, which i did, because i've liked the app. does this hold true to the other apps now that would be " free for a limited time" (eg. modern combat)when they update? does this mean that it becomes free for us to download it and try it in its full version and when an update comes it will be our choice if we pay for it to be updated or just have it in the version when we purchased it for free so it remains 'free'(not updated)? i've thought that since it's already listed in my 'my world' account, it only means that i've downloaded it from the app world, whether i got it for free, on a discounted price, or full price and any price change should not matter and should not affect any updates that would occur in the future.
i've searched the other threads and the suggestions were to notify the support team, which i did, but no response.
i do not complain of app prices or anything. i just want to be cleared on the protocol(if any)in instances like this so i would not sort of notifying the or asking for refunds to the support team everytime it happens.
thank you very much...
