Stone doesn't appear when making move in correspondence games

I seem to be having a slight issue with my games in that when I log in using my phone when I place a stone it doesn’t appear. This has been going on and off for the past few weeks.
My phone is an HTC 1 M9, Android 5.02, using Chrome 44.0.2403.
Sometimes when I reload the page I can place and see the stone but usually that doesn’t work.
Has anyone else seen this or have have any suggestions as to how to fix it?
Many thanks.

As an update it appears to have been google chrome that was the issue. Uninstalled it and reinstalled without all the updates and worked fine for viewing stone after making move. Works fine with Firefox as well.
