My maps are very slow to load, started in the last few weeks

Hi,

Starting a few weeks ago, my maps on the 5 Plus are super slow to load. This has 2 symptoms:

1. When booting the device it stays 2-3 minutes on the "Loading maps" screen before continuing.

2. When trying to use a map during an activity (or not during an activity), it takes the device 1-2 minutes to render the map. After it's displayed, when trying to move or zoom, it takes another couple of minutes to render it again.

I tried to delete all the .img files from the watch and re-install the maps using Garmin Express, but everything stayed the same. I'm trying to avoid a hard reset, but will do it if that will be the last chance.

I checked for corrupted activities, but everything seems fine. 

Anyone have any suggestions?
