ok thanks i am facing one more problem in the same app whenever i am trying to access storage of my phone using image picker even if i am allowing the storage permission it is saying storage permission denied allow from settings . i checked in settings the storage permission is enabled can you please help fixing it.
It would really help if you provided a screenshot of your relevant blocks, so we can see what you are trying to do, and where the problem may be.
Also please let us know the Android version you are using for your tests.
To get an image of your blocks, right click in the Blocks Editor and select "Download Blocks as Image". You might want to use an image editor to crop etc. if required. Then post it here in the community.
