Issues with 9.0.0.10460 on CCX 400 and CCX 500 phones

[Selayanator1]

We use both CCX 400 and CCX 500 with Microsoft Teams and around 180 phones received the Poly 9.0.0.10460 updated before Microsoft pulled it. We immediately started seeing issues with the phones, including losing configurations, blank screens, and dropped calls. Before MS made 9.0.1 available, we tried to downgrade and upgrade manually from the phones using the Poly servers but each would fail. Looking at the phone logs it appears that the download of the software would start and then it would eventually stop and show problems resolving the poly url used to get the software leaving the download incomplete. Once MS made 9.0.1 available we tried to push the update from MS Teams admin center but it also failed with similar erros in the phone logs. Phones that were still at the 8.x code have upgraded to 9.0.1 with no issues but right now we are stuck using usb keys to upgrade those at 9.0.0.10460.  So, just curious if anyone else has experienced these issues. The only other thing I can find in the community is a couple of posts for those with the wifi version of the phones losing wifi connectivity.
