I currently have a Realm which I can connect to via two separate PC accounts. My Switch, however, after loading Minecraft, fails to finish loading Realms. Additionally, when one of the Switch friends is on the Realm, it shows the friend online, on the realm, in the Cross Play section, however, when trying to join, it just says Failed to Connect, Try again later, after about 2 minutes of "loading".

Initially we were using the Minecraft physical card for the Switch, but I just purchased and installed the digital deluxe version as well on the Switch and that also fails.
