Lightroom Mobile (android) keeps its own edits, discard those from Lightroom cloud

Hi !

Here's my situation :

- I took photos with my smartphone, and added them in Lightroom. They synchronized, perfect. 

- I did edits on Lightroom Mobile, they synchronized, perfect. 

- Actually, my mobile phone edits are terrible, and I want to fix these with a computer. But I don't have Lightroom installed on that computer, so I used the web app https://lightroom.adobe.com/. It's basic but it did enough for fixing my mistakes. And it synchronized… ~ish…

When I open Lightroom Mobile, the thumbnail displays the synchronized picture, with my latest edits, the correct edits, the astonishing edits. Then, I open the picture and after loading a few seconds, boum, the old and terrible edits are back. And I can't get the new ones, so I can't work on my picture… 

Hope you'll have something for me !

Thanks for reading !

Rin !
