I have no recommendation, but I wanted to say that I have the SAME issue. I was on a Pixel 3 and I swear that swipe could read my mind. I would be so lazy to swipe/type and I feel it would come out like 95% accurate. Then I switched to a Samsung note, and their swipe always gets it wrong multiple times in a a row. I now tap to type more than swipe.
