SwiftKey Word Prediction disappears

Am I the only one that experiences a loss of word prediction when using Swiftkey? When I am typing for example in Gmail and I switch to another application and switch back to gmail, the word prediction seems to be lost. The only way of getting it back is to hold down the 123 key and go into Settings, then exit. The word prediction is back on again. This could be a bug that the new version of Swiftkey will deal with.
