OK. I am obsessed with stickers. I created my own packs (with 3rd party apps) and imported them to my WhatsApp, from day one ( in 2018?). No problem whatsoever since. Until now. These couple of days, whenever I tried to import a pack, there popped up a box~on the WhatsApp ‘chats’ page~saying “One of the stickers in this sticker pack has an invalid frame duration.” WHAT?! I tried it on my other iPhone. Same. HOW COME?! Have my iPhones gone insane? Or, has WhatsApp decided to ban all other imported stickers so that the users could only create their own stickers within the app? (…But how I hate the ugly white edges of the stickers generated from WhatsApp sticker maker! ) Could the genius at WhatsApp fix this stickers-importing complication, PLEASE? (BTW, importing GIF stickers is still OK, though; I mean with my iPhones 13 & 15.)
