feedback about foreground background instance

[jalys]

Please find my feedback using Foreground and background instance sending SMS.

I have a strange issue,
My app is listening incoming SMS, when i receive an SMS i send a SMS to.

DEBUG MODE & RELEASE MODE

If receive/send background using backgroundinstance .send it works fine, but when i get back foreground i do not receive anymore incoming SMS, well i do not reach onMessage(SmsMessage message), but still somethings happens because i get in the logs.

I/flutter ( 4873): Column is originating_address
I/flutter ( 4873): Column is message_body
I/flutter ( 4873): Column is timestamp
I/flutter ( 4873): Column is service_center
I/flutter ( 4873): Column is status

DEBUG MODE

if i only use telephony Instance , when app is background & foreground to reply to SMS, it works fine

RELEASE MODE

same as previously , it works fine foreground, but you must use background.instance when app is bckg.
Try sending using instance whenapp is background do not works.

i tried calling Telephony.insta
