Error inport addons

I'm experiencing this exact same issue on Android (Minecraft Bedrock 26.51) — no matter which add-on I try to import or which source I download it from (Telegram, MCPEDL, etc.), absolutely no notification appears when opening the file with Minecraft, and the pack never shows up in the add-ons/packs list at all, even though everything worked perfectly fine for me up until version 26.33, so this is clearly a regression introduced somewhere between those two versions and it's completely blocking add-on usage for Android players who don't have access to a PC to work around it."
