2 Yeelight pro spotlights refused to upgrade to latest version

Hi all, May I check how to “force” upgrade my lights to the latest version? Had tried everything using the auto-upgrade version provided in Yeelight Pro app.

Reset and factory data reset both lights multiple times, delete and reinstall yeelight pro app on my phone. These 2 lights kept showing version 1.1.60 no matter how many times I tried upgrade them and both can’t be controlled by the app.

Rest of the lights are on version 1.1.62 and are working ok with the app.

Please help and thanks in advance!
