It's an amazing app! The grammar checker is well configured and spot-on. I use the app whenever I write novels and to ensure I'm getting my words and punctuation right. The only thing that bothers me is that I can't get the Quillbot keyboard to pop up, even after reinstalling the app

I used this app since 2 years ago; it was so easy and efficient. Now the keyboard is missing and becoming so complicated. so dissatisfied. Now the app requires accessibility on my phone, and it always crashes with my other apps. Before this, the app didn't require the accessibility. just bring back the keyboard without accessibility required.

Android Keyboard is no longer supported starting with Android app version 5.0.0. Instead, Android 13 and later users can utilize the Android Assistant, which provides an improved writing experience and is compatible with any keyboard. Please use our support link at https://help.quillbot.com/hc/en-us/requests/new if you have any recommendations.

Dear QuillBot Support Team, I accidentally purchased the QuillBot Premium subscription today through Google Play autopay. It was a mistake, and I did not intend to purchase this plan. Since I do not want to use this subscription, I kindly request you to cancel it and issue a full refund to my original payment method as soon as possible.😭😭
