I lost my iPhone. I went to restore WhatsApp from iCloud. It gets stuck in the restore phase.

I backed it up to iCloud 10 days prior to losing the iPhone.

My iTunes backup is much older, so I dont want to use this.

It initially keep sticking at 182 Mb of 5.x Mb.

I deleted and reinstalled and it did get to 100% and then reported an error.

Now it says "preparing..." and then after 10 seconds says "Couldn't restore chat history".

Please help me get it back :(
