Absolutely, you can use your account across multiple devices, and these will remain synced up with the same meal plans, preferences, etc. as long as you're signed in using the same credentials to access the same account.

Troubleshooting:

- Sometimes updates you've made on one device may not immediately sync if the other was already open. For example, if you made changes on the website and the app was running in the background on your phone, you may just need to close and reopen the app in order to refresh this. 

- If refreshing doesn't resolve any syncing issues you've run into, logging out and back in on one or both devices will typically do the trick. If you try this and still seem to be running into trouble, however, please reach out to our team at [email protected]. If you might be able to include any screenshots showing examples of the discrepancies you're seeing between devices, we'll be happy to take a look and investigate further!
