WMR Controllers losing input after going into standby mode

Hi. I’m coming across an issue with my Lenovo Explorer motion controllers. When launching a project and running a game, the controllers work fine. However, after some time of inactivity, the controllers will switch off to conserve power, and when I switch them back on again, I’m unable to get them working again ingame. I find I have to close the project down and reopen again in order to get controller input working again (which is a bit of a pain).

Has anyone else had this issue, and can you recommend a way to get input working again without closing/reopening the project?

Thanks very much for you time,
