I assume that at this point I shouldn't expect the sweetness to go away.
Any suggestions on how to avoid this problem in the future?
PS - it does have some carbonation but not extremely fizzy.
Agitating the bottles and raising the temperature to 70+ degrees may get things going again, but it would probably be quite slow and may well stall again.
I would uncap the bottles, add a few drops of rehydrated dry yeast with decent alcohol tolerance to each, and then quickly recap. Keep the bottles at 70+ degrees for a 4-6 weeks, and that might do the trick.
