I was using Mementodatabase as a customer visiting record.
I use Contact Field to link the contacts on the phone, and group all the records with that Contact Field, so I can check visiting time of each customer.
but after I done this, everything become quite slow (I just have 50 records), whatever I open record, or save a record back to list, it very very slow, like I have to wait 15 secs for UI active from freezing.
after ungroup from this Contact Field, it become smooth again.
Not sure if there are any ways to avoid freezing when I group with Contact Field? Thank you.
