Great app

خواستم از تیم شما تشکر کنم نزدیک به ۶ ساله که همیشه جزو اولین اپ های روی هر گوشیم بودین که نصب کردم بسیار روان و بسیار خوب لغات معنی شدن و مثالهایی که زده شده از کاربرد عالین خیلی ممنونم بابت این اپلیکیشن.
به تازگی متوجه شدم وقتی که یک کلمه رو سرچ میکنی و نتیجش رو میبینی باید دوباره ضربدر رو بزنی تا کیبوردت بالا بیاد در حالیکه قبلا وقتی slide back میکردی دوباره کیبوردتت میومد بالا الان حتما باید دوباره برگردی به صحفه اول تا بتونی کلمه جدید سرچ کنی
