My app was in bestsellers list last few weeks in utilities section on 2-4 page for Nokia N97 and on 1-3 page for E5 phone. Today suddenly it fall down to e.g page 21 for N97 phone and to page 32 for E5 phone. Now my application in this list comes after some very unpopular utilities with one-two 1star comments. However the sales reports shows every day almost the same amount of sales. How is it possible??? Is it some usual "reset" happen in ovi database or is it nasty database bug which shuffled all the stuff? Should I contact ovi support or is it useless to write about this problem to them?
