Particle Android app

After a 2.5 year hiatus away from teaching, I have once again joined an institution to teach Electronics and Networking. I summarily took out my box of Particle Photon devices I previously used for my class and started by telling the class to download the configuration tool from the Play Store. Imagine my surprise when I realised it is no longer there. Or am I missing something?
I know it has been 2 years since I used a Photon but the app on my phone still works. Is there another place I can download the app from or is there another way I do not yet know about to configure the Photon?
Any help will be appreciated.

The recommended way to configure a device (including the Photon) is
