Hi there,
Our configuration for event tracking appears to no longer be working, as of ~March 13th.
Event ingestion has dropped to 0 since that date in our data -> sources -> ingestion debugging dashboard.
Our setup is as follows:
* Using the old browser SDK, amplitude-js
* Use apiEndpoint config option to override the destination API
* Specify our own Domain Proxy API endpoint, which is an nginx server configured to proxy to https://api.amplitude.com as per your documentation.
I realise the SDK we are using is marked as being in maintenance mode, but I don't see anywhere saying it should have stopped working entirely. Should we expect the above configuration to still be working? Or has something been disabled that we weren't aware of.
