I keep it in around a 60° room on a window sill that gets little indirect natural light, and I water it once a week. The browning began about 2 weeks ago and the yellowing 1.
These are, technically, orchids. They will appreciate a much lighter soil than most houseplants. I believe that your soil may be too heavy and rich.
I would put this into a proper mix of orchid mix and potting soil mixed together. Make sure that the mix never gets soggy, but never dries out. This is the problem with most potting mixes. They are too heavy and will get too wet when you water.

flowers. Prior to that i probably had one per year. We moved to the Fraser Coast 12 months ago and up until recently it has thriv ed. but over the past 2 months the leaves have drooped and I am now tying the leaves up to a stake. I have repotted and initially the leaves would stand up in the morning and as the day progressed they would droop. It is located on the ground floor of our old Queenslander, so is very well protected and only receives filtered sun in the morning through the 6 ft pickets. Help! I also have a smaller white bat plant that is in the same position and is thriving. The plants leaves are approx. 37 centemetres long and just hang. I have tied them up loosely hoping to allow nutrients to still pass from the roots to the leaves but nothing is helping. I regularly feed with Seasol liquid fertiliser and have used liquid compost today.
When you repotted, did you go up just one size in pots? Too big of a pot can cause overwatering. They need a fertilizer for acid-loving plants, and they need a shady location. Here is an article that tells more about their specific needs. See if you can find what is amiss.

I have a black bat plant right next to it and it flowers all the time.
This can be due to slight environmental differences, or age.
Make sure that it does not receive too much light, as this can halt flowering.
It can take up to three years to see the first flower, so if it has not been in ground or established for that long, then patience may be all it takes.

Appreciate the difficulties with germination. Is it possible to obtain an actual seed pod rather than a packet of seeds?
You can likely find seeds or seed pods from local nurseries, or online. We don't recommend specific places to purchase.
When growing these from seed, it can take several years to see the first flower. They are very slow growing, and that speed will be controlled by how closely you can mimic their native habitat. Generally, it is accepted that the first flowers will show up after the first two leaves have developed and matured to full size.
