Just signed up for Pro. Did my Review sentences get reset?

Hi all,

I’ve been using the free version of Ecosia for a few months and decided to pay for the Pro version today.

I noticed, however, that it seems to have reset the counts on the sentences I am reviewing. Eg all sentences are ‘new’ now, even though I swear I have seen them before.

I still have my progress bars however.

Is this just me or a bug with Clozemaster?
