We noticed that you have logged this issue in your last post in this thread
and our developers have logged this as a bug and already planned the fix in their TODO list as discussed here
quote from the forum post reply:
I have investigated the case and have found the reason for the issue you are facing: there is a small bug in the way GridLineAnnotation interacts with the DateTimeContinuousAxis on Android. We are going to log this issue in our TODO system and fix it immediately for you. You will be able to access the fix using the @next tag of the plugin on npmjs.org. I will make sure to notify you as soon as the fix is ready (will be a matter of a day or two).
We will update the information as soon as we have a stable solution to this issue and we will ping you so you could test your project with the next
version of the upcoming release.
