When trying to add a photo straight from my phone I keep getting invalid photo URL messages. I’m sure I’ve posted here straight from the phone before with a photo. Maybe not & it can’t be done…
@vanessa I’ve seen that before on occasion; I’ve attributed it to various communication issues between the app and my website (poor network connection, the fact my host has some sort of cache server that occasionally returns a 405 HTTP error and requires me to do hard reload when moving between pages of the WP Dashboard…). For me, trying again always succeeds (well, once I may have had to try twice).
