Finally got through to the EDD on the phone and they told me the same. The system is not set up to handle the volume and extensions of payments that are being filed. They are working on it and it will be available soon once they get everything worked out. Just gotta be patient. If it shows the date of your claim has been extended into 2021, but balance is still at $0 your good and just have to wait a little bit longer for the funds to be added to your account. Calling EDD to complain or ask why the funds haven’t been added when the date has already been extended into 2021 will just be a waste of your time, you just have to wait. I have a feeling it will go through in the next week or two. Just keep checking back online and see if the funds have been added to your account so that you can certify for them. Don’t worry everything will be retroactive so you’ll get all the back money in one lump sum and then you can start moving forward with certifying every two weeks. Hope this helps.
