@FrankD: Open Jolla Store. Pull down "My Apps". Check that you have "Android App Support" there. If not, go to category "Jolla" in Jolla Store and install "Android App Support".
Next, tackle Aptoide Store following the instructions of Sailaway.
If it keeps failing let us know which phone you have, please.
Please try the following: Check the Jolla Store to see if the Aptoide Store is installed. If so, uninstall the Aptoide Store. Then install the Aptoide Store again via the Jolla Store. In my case, this approach worked regularly. Regards!
Greeting!
