Your charge voltage is too high and causing BMS protection, that's causing full charge protect error and turning off the charge path.
Change the Victron charger to lithium default mode , user select ( expert mode) absorbtion 14.2 volts, float 13.5 volts, equilisation disabled, temperature compensation didabifled, absorbtion duration 30 minutes, adaptive absorbtion disabled. If the battery charges successfully with these settings and the charge MOS stays on , keep these settings as working values.
The apps giving you SOC depend on certain voltages being achieved in the battery , either high volts setting the 100% or low volts setting 0%. The battery will need cycling several times for a more correct SOC reading.
When charging from solar if the voltage exceeds 14.0 volts with some current still flowing into the battery, ( the BMS charge MOS being ON), then consider the battery full, ( greater than 98%).
If when charging with the revised charge voltage suggested, you still encounter the charge MOS switching to OFF , the charge voltage , absorbtion volts, will need lowering, down to 13.8 volts if necessary, whilst in this lowered voltage condition increase the absorbtion duration to 6 hours. This will give the battery more time to balance the cells.
You haven't given details of your shore power charger or the device that indicates SOC when on shore power, these details will be useful.
The decline you see in charge state suggests the reading is voltage based. This is to be expected, once charge voltage is removed, the battery volts will drop and settle to a resting voltage, this will be in the range 13.4 volts +/- 0.05 ( no load or charge).
What you are seeing is a battery where the cells are slightly out of balance, this is common . What happens with a high charge volts of 14.6, is that each cell (if they are exactly the same), would reach 3.65 all at the same time. This is unlikely, well before 14.6 is reached, one cell will exceed the protection level, ( 3.65) and the BMS will shut down the charge path.
It's not a serious issue and unfortuantly battery manufactures/suppliers continue the recomend 14.6 volts as a charge value. This causes confusion and worry to users.

Thanks so much for the explanation. I did not realize that the 3rd decimal was that crucial to the equalization. I can't tell much today since it is stormy and overcast, but the BMS on the battery still shows 60% SOC, however the chargeMOS is green (on). The volts from the solar panel are very low (clouds) but the amps are up, so the Victron app is actually reading MORE watts, (at 20-25W) than it showed the panel putting out on the full sun days (on those days the volts are high but the amps are almost zero, so the watts are around 7W). So it appears that I'm getting more charge on the cloudy days than when the panel is in full sun (25W vs 7W). Neither are very good numbers for a 200W panel and aren't doing a thing for my SOC.
The shorepower charging goes through the WFCO converter I think. I recall having to play with the "automatic detection" to get it to see the LiPo battery. The battery indicator inside the RV indicates a full battery. The BMS on the Powerurus says the battery is 60%. I haven't plugged into shore power in several days as I have been watching this whole solar thing. I'm inclined to believe the BMS on the battery, but the rest of the system is acting like the battery is fully charged.
I don't see anywhere on the Victron App where I can adjust Most of the settings that you and Powerurus have indicated, but I have made sure that the settings that I do have access to match what Powerurus put in their email that I received this morning:
