I have experienced no end of problems on the PlayStations bedrock (Cross-play) edition.
When loading it gets stuck for a good ten minutes in the Wavy bars loading screen. I recently had to uninstall and re-install due to it not loading at all and displaying an error code. After a fresh installation all was working fine again. Normal loading times etc but again today it failed to load. Then after I restarted the PS4 it loaded but took about ten minutes.

Also is the "locator map" in game meant to Teleport your location dot to centre and stop revealing map?

I have 2 maps that I think are broken. I went out walking then my locator dot on map Jumped to centre and direction I was heading wasn't accurate. Almost as if it had stopped tracking the x or z axis I created another locator map functioned fine until I had map equipped in off hand slot and compass in main hand the moment I took out the compass my location jumped to centre of locator map and no longer reviled the map terrain etc ( Please note. The Map issue is experienced whilst cross playing with a PS4, switch, and pc, PS4 is hosting. Experience the mapping issues on win10)
