I just upgraded to the LR Mobile premium and I hoping they had better font options for the watermarks. They only have 4 fonts!!!! Spoke with tech support and he said they don't have room for anymore. Well how about better fancier fonts? I have a Note 10 Plus
Currently, Lightroom Mobile (Android and iOS) are limited to default system fonts supplied by the device OS. We do plan to expand font availability as part of our improved watermarking. I can't share an ETA at this time.
