i'm in the same situation. i used to ride with straps, and upgraded to clipless. the transition was nothing for riding on my road bike - i was used to the idea. i've been riding recently for the first time off road and clipless.
struggling in tight areas too - i'm used to twisting my ankles for leans when moving slow. i clip out at the most inconvenient times... either that or i DON'T clip out, but can't get the right lean (it's a habit i'll break).
to solve my problem i'm going to drop the tension on the pedals (running Shimano M520's) so it's easy to clip in and out. i can clip out and still balance, but i find it a hassle to clip back in 'cause the tricky bits last a while - i just don't have the time to pull a revolution or two - gotta be in in maybe half a crank!
maybe you can drop tension too? if not, just ride and get used to it. takes time, for sure.
