Preview not updating after profile change

Hi everyone,

I encounter a problem regarding color profiles sync in Lightroom mobile IoS. 

- I have a set of negative scans that were color inverted in Lightroom CC windows using Negative Lab Pro, which comes with a custom color profile.

- the color profile has been synchronized correctly on Lightroom mobile IoS.

- the preview appears incorrect on mobile. However, any change in the 'develop' module on mobile will change it back to a correct preview.

Has anyone faced this problem with color profiles? Does a workaround exist?

version: Lightroom Mobile 7.5.2 A35FE5/58 on iOS 15.6.1
