I can't upload 30 min videos

I even tried a 5 minute one just now. It won't work 😕
I've changed the frame rate per second ( found that via Rumble help) but I've not had any luck with any video other than this 30 second update. But thank goodness I've been able to tell you I've got 2 full sized videos sitting here that I cannot upload. It's a crying shame and I'm so sorry. Please forgive me and PLEASE ask youtube to give me my channel back? Via twitter is best or emailing guess but they've blocked my email address now and I'm banned from twitter.Ill be back as soon as I can. Please forgive me. Im missing youtube so much it hurts me still.
Got to keep going though. And I will.
Love you all. Wally xxx
