Disgusted that this has been left to go on all these months. For me its only begun in the last several days and I've been pulling my hair out with it thinking was it my pc at fault and so on, and spent many hours and money wiping my pc to resolve etc, including being unable to work.
Obviously with receiving frequent page cannot be displayed type messages having to refresh plus downloads failing. Xbox services pretty much do not work at all.
This has caused me allsorts of problems trying to purchase goods too where pages fail during making payments and then duplicate transactions!
For me, the downloads issue can be easily replicated by using a premium debrid service, however this would be harder for Three to test without signing up to that service. If I download a file in Firefox, the file begins to download no problem. Once the file hits 99% and finishes it pretty much always says download failed. If I then press retry 1-5 times it eventually says complete. In Chrome and Edge however, when try to download the files, it gets to the end of the download then restarts from the beginning.....over and over and over again. On a mobile phone the files say successfully downloaded but are fully corrupted. The PC is not at fault, in the end I took it to nextdoor and no issues at all to rule out something on my PC
After reading "some" of the latter pages of this thread I see that VPN being engaged seems to not cause the problem, which reflects what I've tried. I also noticed that the logging of downloads on the Debrid service from a few days ago started reporting ipv6 addresses being used. Maybe coincidence but I doubt it. I then manually changed APNs to some of the different ones and specifying IPv4 only, but same problem occurs (the debrid service does report ipv4 address).
