Which browser are you using? Safari Version 13.0.1 (14608.2.11.1.11)
If you’re using a desktop or mobile app, what’s the version number of Dynalist? Using web based
Are you using any third-party scripts for Dynalist, e.g. PowerPack? No


Additional comments

I am just starting out with Dynalist but get foiled with each attempt. I’d prefer not to have to use Firefox but will if it is the case that Dynalist does just not work with Safari.

Thanks

That’s weird. Does the same issue happen if you try to use the demo app at https://dynalist.io/demo

Also does this happen on another browser?
