I just re-downloaded the app to my phone. It was super useful before, but now it's a floating, constantly-on suggestion, or I have to leave the on/off button in my notifs. Before, it was listed under my keyboards, and I could just use it when I was ready to edit a completed piece. Also, it won't show me where in the Doc it's questioning, so I can't see the context!!

After the last update, the mobile keyboard got worse. Now, its glued to the top of the screen so if you have a large phone it can't be conviently reached. It still vanishes every now and then, the only trick is to just open it in another app. Then it says I don't have the right Android version, I have an S10 and I'm pretty sure I'm up to date despite the old phone. I think its supposed to crawl back down to reach when an error is detected but it doesn't detect anything anymore. Still useless.

5/31/24: I like being able to have the option to use Grammarly with Gboard. 8/30/22: Overall, Grammarly is my selected regular all-the-time keyboard. A while ago, I sent in an inquiry to support why the ability to highlight words and toggle their capitalization status stopped working. The reply was this was never a feature (which is not true); I was disappointed! Now the cap toggle is working again; yay! Thank you so much for fixing this much-needed function!
