If you have a multimeter, measure across the output wires of the charge controller. They should read 13.5-14.5v and 4-10 amps in good sunlight. If you’re getting good output from the controller, it means you could be consuming as much dc power as you’re putting in, or battery is near full and bms is not accepting more charge. Resting voltage of LFP is 13.6v. Curious what the app says about voltage and amps coming in. Could be the app or bms needs to be initialized on first use. Additionally, PWM controllers do not reach maximum power point, so you may not get all the amperage being produced by the panels.
