HipadX v1.0_20200904

I just purchased this tablet. I am unable to used for my child to play ROBLOX, to buy or play Minecraft. I try to login to PayPal account to purchase Minecraft but after I put my password I am sent back to the PayPal login page.
On ROBLOX after correctly inserting user and password I have a message “something went wrong. Tri again later” this is for a week and nothing.
I contacted Roblox support team and no resolution I try to believe is something related with the software or hardware or ?
It is aa problem of compatibility of this software or tablet?
What can I do?
