My Apple Smart Keyboard (Azerty) switches to Qwerty when I select the English UK keyboard

I purchased a iPad Pro 9'7 and up to yesterday, I did not use the Apple Smart Keyboard, only the native Apple keyboard in IOS. I am leaving in a French speaking country, so I am used to Azerty Keyboard, and the Azerty Smart Keyboard was not available yet, till recently. I have just purchased my Azerty Smart Keyboard, which is now available. I am immediately running into keyboard configuration issues.

With the native IOS software keyboard I installed 3 keyboards: French, Dutch and UK English, and I set up Dutch and UK English to azerty. It worked fine. I was able to benefit from the spell checker in every language, while keeping the AZERTY keyboard layout. I am constantly switching between these languages, so it was important for me to be able to switch between languages, while keeping the Azerty layout

On my new Azerty Smart Keyboard, I easily can switch between languages using the "globe" key on the left side of the keyboard, but as soon as I switch to UK English or Dutch, the keyboard automatically switches to Qwerty. I checked that my iPad settings did not change: Dutch and UK English are still set to Azerty. So I get confused now.

Of course, I could stick to the french language as a setting for my keyboard, the smart keyboard would retain its built in azerty layout, but I would miss the spell checking option.

Any hint, solution or work around ?
