Hi there 7ef8sio1 the best advice I can give you is to download the apps yourself on GrapheneOS and test them, from a cursory glance at these products I would say that used alongside sandboxed play services they 'should' work. Obviously if they depend on Play and the app store for subscription management you will need a Google account with a payment method.
Only thing I am concerned over is the fact that if it depends on the webview or browser the hardening in Vanadium might break functionality in Blur.
Flex those power user muscles and please give them a go and report back. Your feedback will be valuable to the community at large as unfortunately we cannot test every app available on the Play Store. Maybe in the mean time others who use these services can give a more solid answer.
