I cannot for the life of me get SwiftKey to stop replacing "I'm" with "I". It happens about 50% of the time and makes for some incredibly odd sounding sentences like "hey I going to the store" or "I on my way".
If I just repeatedly flow "I'm" this happens: "I I'm In I I'm I I'm I I'm I I'm I'm" where it alternates between the two, this is after telling it "do not predict I again".
I even turned off autocorrect and it STILL does it.
Device is an AT&T branded Samsung Galaxy S8 running Android 7.0, using SwiftKey Beta 22.214.171.124. Steps to reproduce: try to type (using flow) "I'm".
