It didn't have an issue cooling this summer and although I see no signs of a damp or oily area on anything I can get to, including the most common leaks of the flare connection, I'm thinking check the pressure (only thing found online is ~400psi in heating) and if it seems unreasonably low, get down to spraying everything with soapy water.

Yup. Just put the unit in cooling mode

The one time I had to pump down a mini split without gauges the compressor made a distinct change in tone when the refrigerant was evacuated from the head unit and line set. Anyone else with gauges noticed the same when a unit was pumped down?

When mine was low on freon in cooling mode the large low pressure valve on the outside compressor would freeze up. I would have to put .5 to 1 lb of R410 to get the pressure above 125 and had seen it as high as 180 PSI.
Now R410 is a lot harder to get now but I bought it without a license here. My buddy came over and showed me how to do it and left me a scale and meters.

Not condoning it. But you can use propane as refrigerant... I have done it on a mini split
After watching several utube vids, it looks like the only reliable way to know freon is low is to vacuum it out, weight it, and compare it to the nameplate capacity. Also looks like they don't hold much freon at all and are super easy to overfill damaging the compressor.
Anyone else find trying to find the right replacement part on the senville website very frustrating?
Anyhow, weather is turning bad the next couple days so this project will have to wait.

I have done filling by educated guessing.... but its always a guess.
always use a scale when charging.... if not your really drive blind.

Which remote control do you have? You can access the various temperature readings of the unit and see if any of your thermistors are bad.
Or, if your unit has wifi(and not the stupid Alexa dongle) you can download the midea Smart home app and it will tell you the various temperature readings so you can see if one is off.
I had units that somehow were a lb low so I vacuumed out and weighed refrigerant back in.
Or, you can just add a . 25lb at a time until it starts working correctly.
Remote rg10L1(d2hs)/bgefu1, doesn't say anything in the remote manual about other temperature readings, although holding down one of the remote buttons forces the head unit to display the temperature it's probe is seeing, instead of the head unit displaying the set temperature.

Try putting it in cool mode and with a temp gun check the output air. Dont just go adding refridgerant because someone said "the most common problem is low refridgerant" that's a great way to cause more problems. I would even connect gauges up just yet. If you dont have a temp gun or a set of gauges just call a repairman. How did you vacuum the system down when you installed it?

@Kornbread,
Were you able to check the outdoor temp via the service mode?
Which wifi dongle do you have?
