Hi I have just got a new mediatek zl10 10 inch tablet running android 9.. When I try to get Avast free to protect it I get a message from play store saying this version is not compatible with your device... I have tried many times using different search terms.. I have tried deleting data and cache on the play store app.. Kasperky will download.. AVG also has same incompatible message .. Have used Avast for many years and would like to continue. ..help appreciated mark
