Sometimes batteries that start bloating are not visually bloated yet so you’ll need to do the spin test to be sure.
If you can’t spin the battery I’d try the “kickstart” again. Watch a video at full brightness in the evening until the phone dies, plug-in the phone without the battery, after some time put it in and leave it charging over night.
If the problems still exist make some screenshots to document them and contact support. Maybe they’ll give you a new battery even without a positive spin-test.
To make sure it’s not something else you could borrow someone else’s battery to see if the problems
persist.
