I have been experiencing the same. I filed on the 13th, Monday, was accepted within 15 minutes. Just sat at accepted the first day. The second day, the WMR tool said it couldn’t find anything on me. The next day it was still accepted and today on both the app and the website, it says it doesn’t have any information that matches. I went to sign into my tax account and it shows that my return was submitted and on my transcript it says notice issued on 5-4-2020 and below refund issued on 4-24-2020 so I’m hoping it’s set to come on the 24th
