Edited photos turn yellow when uploading to Instagram

I use Lightroom CC (mobile version) to edit photos on my Huawei P20. I recently found out a problem when publishing photos on Instagram. The photos look perfectly normal when saving them to my device from Lightroom CC but when trying to publish them on IG, there appears yellow colored areas on top of the photos. The areas are rectangle shaped and they appear differently in every photo I try to publish. Both apps (IG and Lightroom CC) were updated a few days ago and after that this problem appeared. I am able to publish non-edited photos normally on IG. If I try to take a screenshot of an edited photo it still makes the yellow areas on top of it when publishing on IG. What can be wrong with the app/apps?
