I've just installed the available build for the Pixel 10 Pro. No issues there. I've got the Google Store, Play Services, and Google fi app installed and transferred my number to my 10 as an eSIM, from my pixel 8 pro, as a phsyical sim card. I can receive/send calls. and I can send texts just fine. However if someone tries to send me a text first, before I send one to them. I do not receive the text. Their phone reports a "did not send" or "failed to send" type of message. One even suggested my phone was offline. If after I send them a SMS, all messages they send me appear to be received just fine. I'm using the stock phone/contact/messages app from Graphene. I've also tried the google phone/contacts/messages app. No change. FWIW it's only been about 24 hours since I initiated this transfer. Does that matter? I've tried removing the eSIM, then clearing the cache/storage for the google fi app. Uninstalling and reinstalling the google fi app, and then re-registering my eSIM. this gets me back to the same state.
Additionally, Yesterday I did have one person send me a text that I did receive. but it took approximately 1 hour to come through. Today they sent me one and I received it almost immediately.
At this point I'm out of ideas. Does anyone have any suggestions for me to try?
