Google Play Store on Chromebook wasn't working properly after installation of the Netskope Chromebook app. I added a certificate-pinned application specifying these URLs and added a steering bypass for ChromeOS. The store works and apps can be downloaded.
Note: We have a managed google play store on android & ChromeOS that only has approved apps.
Spoke with the Google team. Adding an SSL decryption bypass for the URLs in these two links fixed the issue.
