Hi! Thank you so much for letting me know. Mine also seems to be fixed now, and the retry button finally shows 5.5 Thinking on the web too.
I really appreciate you offering to keep your ticket open for me. That was so kind of you, and it honestly made me feel a lot less alone with this issue. I’m glad it seems to be resolved for both of us now. Thank you again!
