Just seems to be one issue after another.
TPLink released a new firmware introducing new encryption through completely proprietary, obfuscated and undocumented algorithms / apis. I added initial support for it within 1 day and spent 10s of hours since then fixing all the issues, even though my camera did not receive the update at that time. If you do not like the integration, do not use it. If you do and encounter issues and want to help, do so constructively or not at all. I, nor anyone else contributing and helping in issues is paid and we do this for free and completely voluntarily.
