Thanks for using ESD! The missing JSON issue sounds like a key/field ID issue. If you have multiple rows starting with the same value, only the last row will be used due to JSON not supporting multiple fields with the same ID. If you are using nested elements, be sure to check out the documentation for more in depth info on what could be happening there!
The account issue is, unfortunately, on Google's side and I cannot do much to work around it. You can have multiple accounts signed in, you'll just need to be mindful that Google will occasionally attempt to use the incorrect account to run ESD, which causes problems. If this happens, you just need to sign out of all but one account, after which you can sign back into your other accounts and use ESD just fine. I'm still looking into potential solutions for this on ESD's end, but is definitely a pretty frustrating usability issue for now.
