I installed Joplin on two phones, a Samsung S10e and a BLU Vivo8. Both have Joplin 2.7.2. The Samsung has Android 12. The BLU has Android 7.0.
Setting up Dropbox sync worked perfectly on the Samsung phone, but not on the BLU phone. I get the expected open this URL in your browser. When I do so, a different app (WPS Office) requests authorization instead of Joplin.
How can I get Joplin to request authorization from Dropbox instead of the office app when using the BLU phone?
