The mobile keyboard just doesn't work. I have to manually trick it into working half the time because after a while it doesn't read or do anything. I liked the keyboard because I'm not very good at typing. But now its become near worthless and just gets in the way half the time. I don't mind moving it but the old keyboard was just simpler. I like the the new ai assistance, thats cool. But everything is just the same so thats pretty much it. I don't even use the AI much but still cool.

Seems to work well for testing about 5 min. The bubble is pretty small and can be moved by touching and holding the G logo and sliding to a new location. Seems to turn on and off by holding the up and down volume buttons for 3 seconds. Looks like is corrects the misspelled words that the cursor line is on. Doesn't work perfectly in all apps tested. Worked well in my email app and after restarting my texting app, it worked. It doesn't bother my existing keyboard function or access.

The keyboard was the entire reason I invested in this app. I'm a writer and sometimes write a significant amount from my phone. It was very convenient to be able to edit that way. That bubble that pops up isn't as convenient, and sometimes it doesn't even pop up at all, leaving me to figure out how to find it. That takes away from my writing and editing time. I have the premium account until November, but I will probably cancel before then.
