Hi Vadim, Great video! only one issue.. do you have any idea why I am getting the error below when I reload the app being my Google Chrome DevTools opened in the Network section? The error says: debugging the remote connection was closed. Reason: WebSocket disconnected I would be grateful to whom could help me. THANKS A LOT!!

Great video! Do you have any video on how we can use Expo as the foundation to build multi-teams Universal Apps? Like, one team would be responsible for the "container" (Design System, Menus, Personalization, Analytics, Login, etc) and each other team would be responsible for a Business Unit related mini-app that runs on that SUPER APP Container (Web and Mobile). For example, a Fintech Super APP that has a menu with different available products for the logged user. Like Banking, Insurance, Loans, Credit Card, Saving Accounts... etc. Each Business Unit would have its dedicated engineering team, that would be as independent as possible from other teams (but maybe dependent on the "Container"), so they have their own release cycle (as long as it doesn't require changes on the Container). Thanks

How Can I solve it?? my app is developed by expo cli sdk 48, unfortunately I have forgotten keystore
Your Android App Bundle is signed with the wrong key. Ensure that your App Bundle is signed with the correct signing key and try again. Your app bundle is expected to be signed with the certificate with fingerprint:
SHA1:
but the certificate used to sign the app bundle that you uploaded has fingerprint:

Is anyone watching this video having as much of a problem as I am in following this video. This video is certainly un-followable. I find libraries I need to install, for the most part, I use "npm". I have a separate environment, to keep versions in check. In using React Expo 49, I cannot use Figma and Locofy (code builder), nor does it work with BLE. I've been bashing my brain trying to get these things to work. Wouldn't be wonderful if the host would make himself available for questions. Perhaps someday, he might contact me. In meantime, it any other viewers who got it to work, and follow the instructor, please reach out to me.
