Lightroom mobile histogram not working properly

A recent update (I don't know exactly when) caused an issue with the histogram on Lightroom mobile. I found this error to appear on my iPad as well as on my iphone. When moving sliders the histogram changes normally. But since a few days only the first change is being shown on the histogram. After that the histogram is not being updated anymore and from time to time I don't see the histogram at all. Closing the photo and reopening it helps for one more step. But it's not very handy to reopen a photo all the time.

could you please apply a fix?

Thank you
