Been a "pro" subscriber at $120/year for several years. Until a few months ago, worked well. Occasionally upload failed before completion but this was a rare event. Now, this happens with every upload. I was advised to restart my (wired, no use of wifi) router, use VPN, not use VPN, block firewall, change firewall settings, use Firefox, use Chrome, Opera, etc.. None of these made any difference. If I try to upload a file of 2 to 6 GB, it usually stops advancing anywhere from 5-10% to 99% and can stay that way for hours. Something has changed with WeTransfer. Cannot recommend a service which used to be OK but has now definitely become costly and useless. Sorry.
