Hello @Ayan-MrcZ thanks for reaching out to us about your issue trying to purchase credits from the Connect overlay.
We have activated a 24-hour delay for players when they are attempting to make multiple purchases in a short space of time. In this instance, you may receive an email from Ubisoft advising you of this delay or see a message saying 'Please try again in a few moments'
As this issue has been affecting you for over 1 week, please check the following steps, to rule out a few possible causes of this purchase issue >
FIX 1: If using a VPN, please disable this before making a purchase and please make sure to use the correct currency for your region
FIX 2: Make sure your game has been fully updated
FIX 3: When attempting the purchase, have you selected your payment method by clicking on the payment method image and have you checked the terms of purchase options?
FIX 4: Are you able to purchase any other credit amounts at all, or are all credit amounts not working for you?
FIX 5: If you have both the Vulkan and DirectX versions of the game installed, please try making a purchase on both versions of the game, as some players have had success on one version of the game, whilst being unable to purchase on the other.
FIX 6: Delete any temporary cache files in your game launchers, that may be using up resources and memory and causing conflict >

FIX 7: Alternatively, instead of using the in-game store, please try making purchases via our Ubisoft Store website. These credits will be available in all PC versions of the game, Connect, Steam and Epic > https://store.ubi.com/uk/all-credits#cgid=all-credits&pmin=0&pmax=280&prefn1=productBrandDisplayString&prefv1=Rainbow+Six&prefn2=productSubBrandString&prefv2=Rainbow+Six+Siege
FIX 8: Steam users > try enabling the Steam overlay and try disabling your Ubisoft overlay, then attempt to make a purchase, in case both overlays are interfering with each other >

FIX 9: Steam users > after following the above step, next, try disabling the Steam overlay instead and enable the Ubisoft Connect overlay, then attempt to make a purchase from Connect.
FIX 10: Steam users > purchases can sometimes be affected by what Steam Store Country you have listed on your Steam account and what currency you are using to make the purchase.
