I can't restore my list of saved words (my data)

I used Swiftkey on my Xiaomi Mi5 for several years (more than 5 probably linked to my google account and recently switched to a Mi5, but when trying to retrieve my saved words (My data) from the previous smartphone, I am unsuccessful.

When trying to link with the google account I don't have any correct word predictions like my Mi5. I have already tried to switch to swiftkey beta, but also to no avail.

The odd thing is that by accessing the "Swiftkey data portal", going to "View data", I can see every list of saved words to export. But they do not appear on my android.

I'm really frustrated with that, and if I want to start over with a keyboard, I'll probably choose to migrate to another competitor that truly provides this feature.
