It’s been doing it more and more for me on Futo as well as time has gone on, but I keep the app disconnected from the internet (GrapheneOS setting) so it shouldn’t be impacted by anything other than training.

It was happening even when I went a while without updating it.

Something makes me think it might be a little self-reinforcing. You get a bad suggestion, you don’t instantly correct it (e.g you press space and then go back to correct it), the app originally assumes you wanted the faulty change, doesn’t backtrack after since you already pressed space)

Maybe I should just turn down the effect or just disable training entirely and see if that changes anything.
