If new photos in your Android Media Library aren't automatically importing into Mylio Photos, please take the following steps:
Re-link the Android Media Library
Open Mylio Photos on your Android device
Open the More Menu (the three dots in the top-right)
Select Settings > Add Media > Add Media Library
If the library was not already linked, your Android Media Library will be imported into a new subfolder within the "Android Photos" folder. Otherwise, you will see a popup that says "Media Library has already been added to Mylio Photos".
The necessary permissions may need to be granted and/or reset within the Android device's Settings app. The exact location will vary depending on which Android device and operating system you have, but it will be something similar to:
Settings > Privacy > Permissions
Settings > Apps > Mylio Photos > Permissions
Ensure Mylio Photos has permission to access Files, Photos, Videos, and/or Media.
If Mylio Photos already has the necessary permissions, turn them off, reopen Mylio Photos, then return to your phone's settings and turn the permissions on.
Grant Access to Additional Folders
To import additional Media Library folders, access to those folders may need to be granted separately.
Open Mylio Photos on your Android Device
Open the More Menu (the three dots in the top right)
Select Settings > Free Up Space on this Device > Customize
Scroll down and select SD Card Access
Grant Mylio Photos access to the folders where your photos are stored
Quit and reopen the Mylio Photos application
