I recently started using the replit mac app rather than a browser. Better for multiple screens. I thought my repl had developed issues cos it was slower all round, even typing user inputs. But switching back to a browser i found it hasn’t slowed at all. Worth knowing guys; i spent a good 4 hours trying to get agent to improve my code for no reason.
Also, the dev tools crash the whole app. So you need to be in browser to inspect and record timings and network for diagnosis…which i only needed cos i was solving the above 
How meta is that??
