The same issue occurs in XF 4.2 version also. Kindly prioritize the fix.

Because of this I am not able to update Xamarin.Forms...

The same issue occurs in XF 4.2 version also. Because of this, I am also not able to update the latest Xamarin.Forms.

Why is this being moved to next sprint again and again. This is a serious issue we are facing in upgrading. Kindly consider this with priority

[jfversluis]

Hello @PaulAnderson02 thanks for the message. I am sorry that this is happening. Unfortunately I don't have any more information for you at this time. We are handling regression bugs with priority.

To move this forward I wanted to have another look at the reproduction to see if I could do anything for you on the short term. The link to that project however seems dead. Would you, or anyone in this issue, be able to provide us with one so I can have another look?

Thanks!

Hi @jfversluis ,

Thanks for the update. Please have the replication sample attached.

I have created a reproduction with just Xamarin.Forms components and then it does seem to work fine. So, is the problem only showing when using this SyncFusion control? Because if so, I'm starting to believe the problem might be somewhere in there. Feel free to check my reproduction and add code to it to show the described bug in case I missed something.
