Android Question Firebase Notifications (manifest error)


Licensed User
Hi, I'm trying to implement Firebase Notifications and have followed the tutorial. I get the error message below, which I believe is an invalid character in an entity reference name. I'm running b4a V6.3 so I used the manifest snippets (not the macros for V8+). I copied the code snippets (unchanged) into the manifest. Is anyone able to suggest what my error could be?

"AndroidManifest.xml:16: error: Error parsing XML: not well-formed (invalid token)"

Any help much appreciated as always.
