Error unable to complete purchase

Hi,

As requested, here is my new topic, even if there are already many topics like it without any solution provided from EA.

Bug is a pop-up "unable to complete purchase" raising on any attempt to buy an item in the PVZ2 shop with money.
See attached file.

There are also a lot of pop-ups "Unable to restore purchase" during the game, when opening any tab such as Shop, Penny pursuit, Arena etc.

My current version is a:10.9.1   
I'm playing the game on an Android device, in French.

I already tried :
Uninstalling the game and installing it again,
Clear the cache,
Clear my Payment information,
Force the app to stop,
Restart device and wifi,
Check the device storage : I still have more than 100 Go available,
Try on another device,
I've the last version of my Android device,
I'm not using any VPN.
