Do check this. Your name is just a small bit of saved data, it shouldn’t affect anything at all (not anymore than gaining xp does, anyhow) unless something huge has been changed.
Did you do anything else, by the way? Such as for example linking a new account or changing device or…? Also, could you perhaps share your name (or if this is private: if it contains anything strange)?
It might help Sarah and the devs, it’s possible they’ve already found out the cause but if they didn’t, any info helps them!
