The core problem is that the form is really big. Let's see if the community can help reduce the size of the form and we can go from there.
As a note to my future self, I tried this:
- XLSForm Online v1.4.1 failed conversion with a recursion depth error.
- pyxform v0.13.1 on the command line converted successfully.
- Collect v1.21 loaded form, but very slow on Moto G5 and a few ANRs.
- Aggregate v2.0.2 failed with Nginx reporting bad gateway and increasing timeouts on nginx config didn't help.
