Hi, We’ve created an app for doing some sums and published it as a web app. It works perfectly on laptops. However if you run the app on safari mobile and force close the tab, then reopen the app it stops working, you get a white screen. Even restarting my phone or trying to open other published thunkable webapps results in the white screen. Anyone come across this? The deployed app: [https://thunkable.site/w/rRDIp5Zsb](https://thunkable.site/w/rRDIp5Zsb) I see the below errors in the console: [Error] Failed to load resource: the server responded with a status of 404 () (2.38c72ff6.chunk.css, line 0) [Error] Failed to load resource: the server responded with a status of 404 () (main.bb1833f1.chunk.js, line 0) [Error] Failed to load resource: the server responded with a status of 404 () (2.5933e61f.chunk.js, line 0) [Error] Refused to execute [https://thunkable.site/static/js/2.5933e61f.chunk.js](https://thunkable.site/static/js/2.5933e61f.chunk.js) as script because “X-Content-Type-Options: nosniff” was given and its Content-Type is not a script MIME type.

Not sure how to delete a topic… This seems to be fixed this morning. Potentially a temporary glitch ---
