Custom skin pack skins cannot be selected

Does MCPE-152132 describe your issue?

MCPE-152132 it's not the same issue as this

The UI in your screenshot does not look like the vanilla UI. Are you using any resource packs? If so, does the issue still occur if you disable them?

It is the newest official vanilla 1.18.10, I don't have any resource packs
I edited the image a little bit to hide one Skin pack

I am seeing that this interface does not appear to all people, so it seems that it is from the Mojang servers and it only appears to certain people
idk

I just received the new UI and can now reproduce this.

I can select a skin from an imported skin pack in the preview (classic UI), but not the beta (updated UI). In the preview, I had to wait a painfully long time for the Marketplace to sync after pressing the create skin button, but I was able to equip a custom skin eventually. If I select a marketplace skin then select a custom skin, I experience MCPE-152132.

i can say it is like this in the 1.18.12 update on windows and not in the preview app as that has the old ui for me so if i copy the same skin pack to that then equip the skin it works and syncs over

From what I've seen, it seems like the "Show in store" button may be the culprit. As you'd expect, custom skin packs fail to be in the store for obvious reasons, but the game seems to wait for that "show in store" button to load. Since it never will, the UI never updates to display the equip button. An easy fix should be to disable that check for when a custom pack is loaded.

This bug isn't just windows 10 either its also Nintendo Switch there is a skin pack called the Mario Mashup Skin Pack and I feel like the mashup is technically a custom skin pack as it's not available in the marketplace. So hopeful when they fixed this issue it will help out the switch players as well.

i have the same problem on windows 10

Someone created a texture pack that solves this

Tested D Flog Flag's fix, it does not work to fix this issue.

CoinxTM35 Be sure to:
1.- Not having other active texture packs
2.- Activate the texture pack
3.- Make sure you are experiencing the bug shown in the report and not similar ones
4.- The "equip" button appears in the corner with the texture pack

Do you mean skin packs or texture packs they are different and texture packs are not a part of this issue, if you meant skin packs then the fix does not work. Texture packs don't have an issue for me currently although I don't know about others.

Hopefully a update is on the way usually it takes two months for new bedrock updates and I think they is a way for windows by using a file similar to what you sent.

Just tried the texture pack that D Flog Flag provided. I can say that this 100% works for me. I'll show screenshots of proof but basically, I removed all texture packs I currently had enabled, then enabled this fix texture pack and placed it on top of the default pack. When I go into the dressing room, all custom skins now show the equip button for me. 

Thanks for the help, D Flog Flag

Didn't mention in the picture but yes when you equip and back out to main screen, the skin is equipped. The skins also work as expected in worlds even when the fix pack is not in use afterwards. 

I retract my previous statements as this does appear to fix it, also as long as you have the skin fixer texture pack above any other active packs you'll be fine.

Minecraft: Bedrock Edition - Beta & Preview 1.18.30.32/33

Fixed issue where info and buttons did not appear for downloaded skin packs

The next update should resolve the issue.
