It is so costly and I cannot restore it in a new phone. Emailed them for help but there is no reply!

I am writing this review for LDOCE I purchased with around S$ 42 from this developer since I have not received any single reply mail to my complaint email for LDOCE that has reached termination of working properly. All of the necessary evidence and minute insights have been attached to the recent mails to the provided contact support email address in the application’s settings. Dear LDOCE Team( from English Channel),Splendid day to you! I hope this post finds you with calmness in the chaos and serenity in your soul. I am reaching out to you with reference to your application named Longman Contemporary of English which I purchased through my master card via Apple Store on 16th July 2021. Since then I have been exploiting or expending the resources in the application with no technical issues until a few prior months when I could no longer access any of the content inside the application. I have already either attempted all of the potential features and options in the app’s settings including resetting or refreshing, or even deleted and reinstalled more the enough. Nevertheless, it seems that there is nothing I can do aside from official pragmatic support and a reasonable solution via email at present. No matter how I tested with any of the possible solutions when they have not been resolved, I presume the whole issue is out of my reach. Whenever I try to look up a word in your so-called ideal dictionary ( the latest edition), I can see nothing in the entry. To put it another way, even after searching for every single word by typing it individually in the search bar, no results of definitions are given as before. Hence, when I can not view any words, what is the primary purpose of your around S$42 dictionary application? It is rather frustrating that it has been more than 3 months since I could not see anything else in it, however, I strived to look for definitions as usual. How you will remedy this disappointing malfunction or defect with your one-time purchase pricey dictionary app, specifically for me? I must regain access to the app from any of my iPads. The same problem arises on both of my iOS devices. The one that I am currently utilizing is the latest iPad Pro with its updated iOS version together with the up-to-date download version for LDOCE as well. As you can see in the attached evidential video, it could show nothing else whatever I tried inside. Given these, I demand any logical and practical long-lasting solution to this flaw or imperfection from your team. I am going to send this sensible complaint for my rights followed by my investment in yours out to multiple places including Apple Report until you provide me with a workable solution. I would sincerely appreciate it if you could revert to me along with feasible support or a refund as soon as possible. I insist you to read this email through comprehensively from top to bottom for detailed better insights. I am looking forward to receiving your response in a little while. Have an extraordinary day!Yours Sincerely,Eric
