Cannot download the offline sound for the examples

The online sound of the examples are working. However, It takes forever to download the offline sound for the examples( in-app purchase). The reason may be the files are too large (may you zip them) or the server is too far from the user.
May you put the files on Azure, AWS or any cloud provider, so users in America can reach to them.
The app is great! Thank you!

Developer Response ,

The files are just huge. The device is probably going to sleep and it is timing out. Keep the app in the foreground. Try when you go to sleep -leave plugged in.
The server is in Tokyo on a high-speed line. Fastest is 10 minutes in Japan. Slowest is all night in China... Europe goes through Turkey... I don't know where your bottleneck is.
All the sound files are compressed already, ZIP does not make them smaller.

Useful dropdown menu has been removed

Latest update removed the option of being able to use the dropdown menu which was a very nice feature. In fact most of us bought this new version because of that new and very useful feature. Now it is no longer available ! The app library picture still shows the dropdown menu option but it is no longer available in the app itself. This needs to be corrected asap so that people do not get shocked when they open the app and find out that the dropdown menu does not exist.
The developer put up the new version for sale with all the nice features and now with this update many of those features are gone. It appears that the app has been downgraded to a basic dictionary with only a few features left. I paid over $30 for this app.
Now I ended up with an expensive app that I can no longer use for my note taking in my studies.

Developer Response ,

Have you looked in About > Settings? You probably have turned off the menu feature.

The developer who answer the reviews is not the same from support desk

The person who answer the review tells me that whatever I’m Observing as a bug it’s not, actually he or she says it’s a expected behavior.
The support desk tells me that is something it should have been fixed in the update but it wasn’t . I can’t make myself understood if the support desk hardly ever answers nor even check the pictures of video where you can observe the bug and replicate it.

If the developer is going to answer me to my review , I think that the minimum thing he or she could is to make make sure someone have previously answer to me from support desk

How can support desk tell me it’s a bug and that it should be solved with the update but it isn’t after so many months

And then you developer comes here and answer reviews telling me it’s not a bug, it’s a expected behavior

The minimum thing your support desk could do is to review the email and at least open the videos and pictures proof that there is a bug

But support desk or customer service hardly ever answers

Developer Response ,

As the support desk should have replied to you and as as we did here previously, the flashing you are referring to is NOT a bug but a feature. It is to show the target the user is jumping to when it is not a headword.
