New update to MCPE from 16-Apr-2020 lags realms to unplayable

Trying to build a collection minecart track, block lag is massive. Can't open any chest types, minecarts don't push, hoppers don't move items, have to exit and re-enter to make any changes happen. After relogging, if I can without rebooting the game, lag hits within 3 to 5 seconds. Start all over again. Lag is even present when trying to load the realm. Have great 4g signal on phone but can take 5 minutes to get realm to load past getting resources.
