Your signatures will not be displayed normally. Because: 1- The maximum volume of characters should not exceed 4000 (preferably if they are 3700) 2- The signature should be on lines no more than 3. On a full member you have 4 lines. This means that one of them will simply be cut off 3- Your logo is too large, too high, the allowed logo height should not exceed 20 lines in height and have a format of 2pt (this format is the same on all browsers)
