Docs to go - can’t sync

I’ve been using Docs to Go on a couple of win 10 laptops and now on a win 11 model. I’ve been syncing to iPhones but most importantly to an iPad. Everything was going well until 3 weeks ago. Luckily I synced before my string of bad luck. My laptop died. Luckily it was under warranty and It’s okay now. Then my almost 4 year old ipad died. Icare in pattaya’s central couldn’t help. I bought a new 12.9 inch iPad at the store selling apple stuff one floor down. Luckily I had just backed it up.

When I tried syncing on Documents to Go I could not add a new device. I started docs to go, clicked on add device, clicked on new device, went to the new device identifier screen, with my iPad’s doc to go showing the code for a new desktop but the laptop didn’t recognize it. Both units were on the same wifi, cellular data off on the ipad, vpn off on both units, disabled malwarebytes and avast on the laptop, but the ipad wasn’t recognized. I’ve tried over and over.

What do you suggest?
