Hi @Sarah_Ackley @Roman_Isaakov @CelineGr,
Sorry for the trouble you've experienced opening projects, and thank you for your patience while we got to the bottom of this issue. We have found that users with slow (or unstable) connections are sometimes unable to complete the process to open a project before our internal "idle" check runs, resulting in the "your project went to sleep" message re-appearing before the project is open.
We've just released a change to mitigate this problem (although very, very slow connections might encounter another aspect of it that manifests in a similar way). Additionally, while the project is finishing up its "open" operation, you may see a white screen where the IDE should be, but if you wait through that, everything should eventually resolve.
We are looking into ways to further improve this experience when connections are slow or interrupted, but I wanted to let you know that you should be able to open projects now by waiting through the white screen.
Please let us know if you're still seeing this behavior, or if you have any questions about this .
Best,
Mel
