Every thing fine but......

Should be the option in app or through system ui for app to enable dark mode support in ios 13

i have this issue with iphone 6s on ios 13

In ipad mini(1st generation) ios 9.3.5

The app is so slow to search the words and when we search one word must be quite the app and then enter the app again to search the second word & sometime it crashes

Please resolve this issue & bring dark mode support on ios 13

Thanks for your best support🙏🙏

Developer Response ,

We are waiting for Apple to release the update.

SoroushKM ,

too generous, yet useless margin - split screen problems too

1- I don’t understand what’s with the right-hand margin?! it’s too wide. I guess it to be a bug.
2- One other problem is that in portrait split-screen mode, it doesn’t show the definition part completely( the black column on the left covers some part of it).
3- Sometimes in IOS 13 split-screen mode when you go back to full-screen mode, the fonts get larger.
4- After updating to IOS 13, the search box have gone bigger and out of frame.
Thank you for your attention

Developer Response ,

Issues with iOS13 are fixed and we just need to wait for Apple to allow the update to go through.

The last update is a great new option but is not working on my iPhone X. When I use this share option there is no way to close the dictionary when it opens.

Thank you
