I like most of the Grammarly products. I'm a premium subsriber and have been for years. However, recently I've been having issues with their keyboard on my Samsung S21 Ultra. For some reason Ilthe letters on the keyboard get tiny. It is a bug. I have to select a different keyboard and then go back to the Grammarly keyboard to get the letters back to normal size. I've also uninstalled it and reinstalled it and that works temporarily. I think this was happening before the UI6 update from Samsung.

I finally purchased the prime service, at an on sale rate, after years of using the free service, on and off. I'm annoyed because the app keeps turning off the "Writing Assistant" function. every time I highlight a paragraph for suggestions the "Writing Assistant" function turns off. when it turns off I receive a message that states "NO INTERNET". everything else on my system works fine on the same Internet that supposedly is not connected. I'm not happy with the purchase. Waste of money for me.

There is a bug that makes it very hard to log into your Grammarly account. Also, when you add an app to the "Blocked apps list", the Grammarly bubble still shows up in the blocked app lol. That being said, the core functionality is really impressive and helpful (as evidenced by its use on desktop and web) but the bugs on the Android app make it very hard to access that core functionality. Once this is all fixed I will happily set my rating to 5 stars.
